Description

Technical Field

[0001] The embodiments of the present disclosure relate to the technical field of data transmission, and in particular to a method, device, system, equipment and medium for encrypted transmission of digital currency data. Background Art

[0002] With the development of data technology and science and technology, the processing volume of digital currency data is increasing day by day, and in many cases, it is necessary to encrypt and transmit digital currency data to multiple recipients. For example, in the prior art, when a client needs to send certain digital currency data to an acceptance agency, a digital research institute interconnection platform that is higher than the acceptance agency, and a payment collection operation agency that is higher than the digital research institute interconnection platform, the client usually encrypts the digital currency data for the first time and then sends it to the acceptance agency. The acceptance agency decrypts all the received digital currency data, and then encrypts the digital currency data that needs to be uploaded to the higher-level digital research institute interconnection platform and the payment collection operation agency for the second time, and then sends it to the higher-level digital research institute interconnection platform. The digital research institute interconnection platform decrypts all the received digital currency data, and then encrypts the digital currency data that needs to be uploaded to the higher-level payment collection operation agency for the third time, and then sends it to the payment collection operation agency. The problem with this transmission method is that after the low-level receiver decrypts the received encrypted data, it can see all the data required by the high-level receiver, which poses a risk of sensitive information leakage. In addition, since each level of receiver needs to perform encryption before uploading data, this will result in a longer transmission time for the entire data and lower transmission efficiency.

In addition, for the sake of clarity, parts not related to the description of the exemplary embodiments are omitted in the accompanying drawings.

[0068] In the embodiments of the present disclosure, it should be understood that terms such as "including" or "having" are intended to indicate the existence of features, numbers, steps, behaviors, components, parts, or a combination thereof disclosed in this specification, and are not intended to exclude the possibility of one or more other features, numbers, steps, behaviors, components, parts, or a combination thereof existing or being added.

[0069] It should also be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other. The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0070] The technical solution provided by the disclosed embodiment performs hierarchical encryption on the digital currency data to be transmitted according to the recipient information, and sends the hierarchical encryption information corresponding to the recipient identification information and the encrypted digital currency data to the recipient. The technical solution enables different recipients to obtain the encrypted data they need, thereby avoiding the risk of sensitive information leakage caused by other recipients being able to see the data required by all recipients. At the same time, the technical solution only needs to perform hierarchical encryption once on the sender, instead of the existing technology, where each level of recipients needs to perform encryption operations before uploading data, thereby saving data transmission time and improving data transmission efficiency.

[0071] Figure 1 A flowchart of a method for encrypting and transmitting digital currency data according to an embodiment of the present disclosure is shown as follows: Figure 1 As shown, the digital currency data encryption transmission method includes the following steps S101-S104:

[0072] In step S101, the digital currency data to be transmitted is obtained;

[0073] In step S102, the digital currency data to be transmitted is hierarchically encrypted according to the recipient information, wherein the number of recipients is one or more, the recipient information includes the recipient identification information, the data requirements required by the recipient, and the recipient encryption requirements, and the recipient encryption requirements include the recipient encryption level requirements and the recipient encryption algorithm requirements;

[0074] In step S103, hierarchical encryption information corresponding to the recipient identification information is generated;

[0075] In step S104, the hierarchical encryption information and the encrypted digital currency data are sent to the bottom-level recipient.

[0076] As mentioned above, with the development of data technology and science and technology, the processing volume of digital currency data is increasing, and in many cases, it is necessary to encrypt and transmit digital currency data to multiple recipients. For example, in the prior art, when a client needs to send certain digital currency data to an acceptance agency, a digital research institute interconnection platform that is higher than the acceptance agency, and a payment collection operation agency that is higher than the digital research institute interconnection platform, the client usually encrypts the digital currency data for the first time and then sends it to the acceptance agency. The acceptance agency decrypts all the received digital currency data, and then encrypts the digital currency data that needs to be uploaded to the higher-level digital research institute interconnection platform and the payment collection operation agency for the second time, and then sends it to the higher-level digital research institute interconnection platform. The digital research institute interconnection platform decrypts all the received digital currency data, and then encrypts the digital currency data that needs to be uploaded to the higher-level payment collection operation agency for the third time, and then sends it to the payment collection operation agency. The problem with this transmission method is that after the low-level receiver decrypts the received encrypted data, it can see all the data required by the high-level receiver, which poses a risk of sensitive information leakage. In addition, since each level of receiver needs to perform encryption before uploading data, this will result in a longer transmission time for the entire data and lower transmission efficiency.

[0077] In view of the above problems, in this embodiment, a digital currency data encryption transmission method is proposed, which performs hierarchical encryption on the digital currency data to be transmitted according to the receiver information, and sends the hierarchical encryption information corresponding to the receiver identification information and the encrypted digital currency data to the receiver. This technical solution enables different receivers to obtain the encrypted data they need, thereby avoiding the risk of sensitive information leakage caused by other receivers being able to see the data required by all receivers. At the same time, this technical solution only needs to perform hierarchical encryption once on the sender, instead of the existing technology, where each level of receiver needs to perform encryption operation before uploading data, thereby saving data transmission time and improving data transmission efficiency.

[0078] In one embodiment of the present disclosure, the digital currency data encryption transmission method can be applicable to digital currency data senders such as computers and electronic devices that perform encrypted transmission of digital currency data.

[0079] In one embodiment of the present disclosure, the digital currency data refers to digital currency data that can be sent, transmitted and processed, such as digital RMB data. More specifically, the digital currency data may be digital RMB transaction data, digital RMB business data, and the like.

[0080] In one embodiment of the present disclosure, the number of the recipients is one or more, for example, the recipient may be an acceptance institution, the next-level recipient of the acceptance institution, the Digital Research Institute Interconnection Platform, and the next-level recipient of the Digital Research Institute Interconnection Platform, the collection operation institution, etc. When the number of the recipients is multiple, the recipient who first receives the digital currency data sent by the digital currency data sender can be considered as the bottom-level recipient, and the recipient who receives the digital currency data last can be considered as the top-level recipient.

[0081] In one embodiment of the present disclosure, the recipient information includes recipient identification information, recipient required data requirements, and recipient encryption requirements, wherein the recipient identification information refers to information used to distinguish the recipient, such as the recipient ID, etc.; the recipient required data requirements refer to data that requires which data the recipient needs, such as the recipient required data requirements can be expressed as the position of the data required by the recipient in the digital currency data to be transmitted, that is, with the help of the recipient required data requirements, it can be understood which data in the digital currency data to be transmitted the data required by the recipient is; the recipient encryption requirements refer to the requirements of the recipient for data encryption, for example, the recipient encryption requirements may include the recipient encryption level requirements and the recipient encryption algorithm requirements, etc.

[0082] In one embodiment of the present disclosure, the hierarchical encryption information refers to the hierarchical encryption information corresponding to the recipient identification information, that is, the hierarchical encryption information can indicate which encrypted data in the encrypted digital currency data is required by which recipient or which level of recipient, and what is the encryption level of the encrypted data and what encryption algorithm is used.

[0083] In the above implementation, the sender first obtains the digital currency data to be transmitted; then, according to the recipient information, the digital currency data to be transmitted is hierarchically encrypted; then, based on the hierarchically encrypted digital currency data, hierarchical encryption information corresponding to the recipient identification information is generated, that is, hierarchical encryption information corresponding to each recipient; finally, the hierarchical encryption information and the encrypted digital currency data are sent to the lowest level recipient, that is, the bottom level recipient.

[0084] In one embodiment of the present disclosure, the step S102, i.e., the step of hierarchically encrypting the digital currency data to be transmitted according to the recipient information, may include the following steps:

[0085] According to the data requirement of the receiving party, determining the data to be encrypted corresponding to the identification information of the receiving party from the digital currency data to be transmitted;

[0086] The data to be encrypted is encrypted according to the encryption requirement of the receiving party.

[0087] As mentioned above, the recipient information includes recipient identification information, recipient required data requirements and recipient encryption requirements. Therefore, in this embodiment, when the digital currency data to be transmitted is hierarchically encrypted according to the recipient information, first, according to the recipient required data requirements in the recipient information, the data to be encrypted corresponding to the recipient identification information is determined from the digital currency data to be transmitted; then, according to the recipient encryption requirements in the recipient information, the data to be encrypted is encrypted to obtain the digital currency data encrypted for the digital currency data required by different recipients, thereby completing the hierarchical encryption of the digital currency data to be transmitted.

[0088] In an embodiment of the present disclosure, the step S103, i.e., the step of generating hierarchical encryption information corresponding to the recipient identification information, may include the following steps:

[0089] Determining encrypted data identification information corresponding to the recipient identification information;

[0090] The receiver identification information and the encrypted data identification information corresponding to the receiver identification information are combined to form hierarchical encryption information corresponding to the receiver identification information.

[0091] In one embodiment of the present disclosure, the encrypted data identification information refers to information used to distinguishably identify a certain part of the encrypted data, such as identification information used to identify the position of a certain part of the encrypted data in the entire encrypted data, etc., that is, based on the encrypted data identification information, the recipient can uniquely determine the encrypted data it needs from the received encrypted data.

[0092] After the digital currency data to be transmitted is hierarchically encrypted according to the recipient information, in order to allow the recipient to uniquely identify the encrypted data part corresponding to it, that is, the part it needs, from the received encrypted digital currency data, in this embodiment, the encrypted data identification information corresponding to the recipient identification information is first determined, that is, the identification of the encrypted data required by different recipients is determined; then the recipient identification information and the encrypted data identification information corresponding to the recipient identification information are combined to form hierarchical encryption information corresponding to the recipient identification information, and the hierarchical encryption information can be subsequently sent to recipients at all levels so that recipients at all levels can accurately obtain the encrypted data they need.

[0093] In one embodiment of the present disclosure, the method may further include the following steps:

[0094] Determining an encryption level and an encryption algorithm corresponding to the identification information of the recipient according to the encryption requirement of the recipient;

[0095] The receiver identification information and the encrypted data identification information corresponding to the receiver identification information are combined to form hierarchical encryption information corresponding to the receiver identification information, specifically:

[0096] The receiver identification information and the encrypted data identification information, encryption level and encryption algorithm corresponding to the receiver identification information are combined to form hierarchical encryption information corresponding to the receiver identification information.

[0097] As mentioned above, the recipient information includes recipient identification information, data requirements required by the recipient and recipient encryption requirements. In this embodiment, the encryption level and encryption algorithm corresponding to the recipient identification information can also be determined according to the recipient encryption requirements in the recipient information, that is, the encryption levels and encryption algorithms required by different recipients. In this way, the encryption levels and encryption algorithms required by different recipients can also be put into the hierarchical encryption information, that is, the recipient identification information and the encrypted data identification information, encryption level and encryption algorithm corresponding to the recipient identification information are combined to form the hierarchical encryption information corresponding to the recipient identification information and sent to the recipient, so that the recipient can not only accurately determine what encrypted data he needs, but also accurately understand the encryption level of these encrypted data and the encryption algorithms used.

[0098] Figure 2 A flowchart showing a method for encrypting and transmitting digital currency data according to another embodiment of the present disclosure is shown. Figure 2 As shown, the digital currency data encryption transmission method includes the following steps S201-S204:

[0099] In step S201, receiving hierarchical encryption information and encrypted digital currency data sent by a sender, wherein the hierarchical encryption information includes receiver identification information and encrypted data identification information corresponding to the receiver identification information;

[0100] In step S202, the encrypted data required by the receiver is determined from the encrypted digital currency data according to the receiver identification information and the encrypted data identification information corresponding to the receiver identification information;

[0101] In step S203, the encrypted data is decrypted to obtain the digital currency data required by the recipient;

[0102] In step S204, based on the receiver identification information and the encrypted data identification information corresponding to the receiver identification information, the hierarchical encryption information corresponding to the higher-level receiver and the encrypted data required by the higher-level receiver are transparently transmitted to the higher-level receiver.

[0103] As mentioned above, with the development of data technology and science and technology, the processing volume of digital currency data is increasing, and in many cases, it is necessary to encrypt and transmit digital currency data to multiple recipients. For example, in the prior art, when a client needs to send certain digital currency data to an acceptance agency, a digital research institute interconnection platform that is higher than the acceptance agency, and a payment collection operation agency that is higher than the digital research institute interconnection platform, the client usually encrypts the digital currency data for the first time and then sends it to the acceptance agency. The acceptance agency decrypts all the received digital currency data, and then encrypts the digital currency data that needs to be uploaded to the higher-level digital research institute interconnection platform and the payment collection operation agency for the second time, and then sends it to the higher-level digital research institute interconnection platform. The digital research institute interconnection platform decrypts all the received digital currency data, and then encrypts the digital currency data that needs to be uploaded to the higher-level payment collection operation agency for the third time, and then sends it to the payment collection operation agency. The problem with this transmission method is that after the low-level receiver decrypts the received encrypted data, it can see all the data required by the high-level receiver, which poses a risk of sensitive information leakage. In addition, since each level of receiver needs to perform encryption before uploading data, this will result in a longer transmission time for the entire data and lower transmission efficiency.

[0104] Considering the above problems, in this embodiment, a method for encrypted transmission of digital currency data is proposed, which performs hierarchical encryption on the digital currency data to be transmitted according to the receiver information, and sends the hierarchical encryption information corresponding to the receiver identification information and the encrypted digital currency data to the receiver. After receiving the hierarchical encryption information and the encrypted digital currency data, the receiver finds the encrypted data corresponding to itself for decryption, and transparently transmits the hierarchical encryption information corresponding to the higher-level receiver and the encrypted data required by the higher-level receiver to the higher-level receiver. This technical solution enables different receivers to obtain the encrypted data they need respectively, thereby avoiding the risk of sensitive information leakage caused by other receivers being able to see the data required by all receivers. At the same time, this technical solution only needs to perform hierarchical encryption once at the sender, instead of the existing technology, where each level of receiver needs to perform encryption operation before uploading data, thereby saving data transmission time and improving data transmission efficiency.

[0105] In one embodiment of the present disclosure, the digital currency data encryption transmission method can be applicable to digital currency data recipients such as computers and electronic devices that implement digital currency data encryption transmission, especially low-level recipients.

[0106] In this embodiment, the bottom-level receiver first receives all the hierarchical encryption information and encrypted digital currency data sent by the sender, wherein the hierarchical encryption information includes receiver identification information and encrypted data identification information corresponding to the receiver identification information; then the bottom-level receiver finds the encrypted data required by the bottom-level receiver from the encrypted digital currency data according to the receiver identification information and the encrypted data identification information corresponding to the receiver identification information; then the bottom-level receiver decrypts the encrypted data to obtain the digital currency data required by the bottom-level receiver; finally, the bottom-level receiver transparently transmits the hierarchical encryption information corresponding to the higher-level receiver and the encrypted data required by the higher-level receiver to the higher-level receiver according to the receiver identification information and the encrypted data identification information corresponding to the receiver identification information, wherein the hierarchical encryption information corresponding to the higher-level receiver and the encrypted data required by the higher-level receiver include not only the hierarchical encryption information corresponding to the receiver one level higher than the bottom-level receiver and the encrypted data required by the receiver, but also the hierarchical encryption information corresponding to other receivers higher than the bottom-level receiver and the encrypted data required by these receivers. That is to say, after the bottom-level receiver receives all the hierarchical encrypted information and encrypted digital currency data sent by the sender, the receiver leaves the data it needs and then transparently transmits the hierarchical encrypted information and encrypted digital currency data needed by the higher-level receiver to the receiver at the next higher level. After the receiver at the next higher level than the bottom-level receiver receives the hierarchical encrypted information and encrypted digital currency data sent by the bottom-level receiver, the receiver leaves the data it needs and then transparently transmits the hierarchical encrypted information and encrypted digital currency data needed by the higher-level receiver to the receiver at the next higher level, similar to the bottom-level receiver. Similarly, after receiving the hierarchical encrypted information and encrypted digital currency data, the receiver at each level leaves the data it needs and then sends the remaining data to the higher-level receiver to realize the hierarchical encrypted transmission of digital currency data.

[0107] In one embodiment of the present disclosure, the hierarchical encryption information further includes the encryption level and encryption algorithm corresponding to the recipient identification information; in this embodiment, the step of decrypting the encrypted data can be specifically implemented as follows:

[0108] The encrypted data is decrypted according to the encryption level and encryption algorithm corresponding to the recipient identification information.

[0109] As mentioned above, the hierarchical encryption information may also include the encryption level and encryption algorithm corresponding to the recipient identification information. In this way, when the recipient decrypts the encrypted data left behind, the recipient may decrypt the encrypted data left behind according to the encryption level and encryption algorithm corresponding to the corresponding recipient identification information in the hierarchical encryption information.

[0111] Figure 3 A flowchart showing a method for encrypting and transmitting digital currency data according to another embodiment of the present disclosure is shown. Figure 3 As shown, the digital currency data encryption transmission method includes the following steps S301-S304:

[0112] In step S301, receiving hierarchical encryption information and encrypted data sent by a lower-level receiver, wherein the hierarchical encryption information includes receiver identification information and encrypted data identification information corresponding to the receiver identification information;

[0113] In step S302, the encrypted data required by the receiver is determined from the encrypted digital currency data according to the receiver identification information and the encrypted data identification information corresponding to the receiver identification information;

[0114] In step S303, the encrypted data is decrypted to obtain the digital currency data required by the recipient;

[0115] In step S304, the encrypted data required by the higher-level receiver is transparently transmitted to the higher-level receiver according to the receiver identification information and the encrypted data identification information corresponding to the receiver identification information.

[0116] As mentioned above, with the development of data technology and science and technology, the processing volume of digital currency data is increasing, and in many cases, it is necessary to encrypt and transmit digital currency data to multiple recipients. For example, in the prior art, when a client needs to send certain digital currency data to an acceptance agency, a digital research institute interconnection platform that is higher than the acceptance agency, and a payment collection operation agency that is higher than the digital research institute interconnection platform, the client usually encrypts the digital currency data for the first time and then sends it to the acceptance agency. The acceptance agency decrypts all the received digital currency data, and then encrypts the digital currency data that needs to be uploaded to the higher-level digital research institute interconnection platform and the payment collection operation agency for the second time, and then sends it to the higher-level digital research institute interconnection platform. The digital research institute interconnection platform decrypts all the received digital currency data, and then encrypts the digital currency data that needs to be uploaded to the higher-level payment collection operation agency for the third time, and then sends it to the payment collection operation agency. The problem with this transmission method is that after the low-level receiver decrypts the received encrypted data, it can see all the data required by the high-level receiver, which poses a risk of sensitive information leakage. In addition, since each level of receiver needs to perform encryption before uploading data, this will result in a longer transmission time for the entire data and lower transmission efficiency.

[0117] Considering the above problems, in this embodiment, a method for encrypted transmission of digital currency data is proposed, which performs hierarchical encryption on the digital currency data to be transmitted according to the receiver information, and sends the hierarchical encryption information corresponding to the receiver identification information and the encrypted digital currency data to the receiver. After receiving the hierarchical encryption information and the encrypted digital currency data, the receiver finds the encrypted data corresponding to itself for decryption, and transparently transmits the hierarchical encryption information corresponding to the higher-level receiver and the encrypted data required by the higher-level receiver to the higher-level receiver. This technical solution enables different receivers to obtain the encrypted data they need respectively, thereby avoiding the risk of sensitive information leakage caused by other receivers being able to see the data required by all receivers. At the same time, this technical solution only needs to perform hierarchical encryption once at the sender, instead of the existing technology, where each level of receiver needs to perform encryption operation before uploading data, thereby saving data transmission time and improving data transmission efficiency.

[0118] In one embodiment of the present disclosure, the digital currency data encryption transmission method can be applied to digital currency data recipients such as computers and electronic devices that implement digital currency data encryption transmission, especially high-level recipients at the next level of low-level recipients.

[0119] In this embodiment, a high-level receiver receives hierarchical encryption information and encrypted data sent by a low-level receiver, wherein the hierarchical encryption information includes receiver identification information and encrypted data identification information corresponding to the receiver identification information; then the high-level receiver finds the encrypted data required by the high-level receiver from the encrypted digital currency data according to the receiver identification information and the encrypted data identification information corresponding to the receiver identification information; then the high-level receiver decrypts the encrypted data to obtain the digital currency data required by the high-level receiver; finally, the high-level receiver transmits the hierarchical encryption information corresponding to the higher-level receiver and the encrypted data required by the higher-level receiver to the higher-level receiver according to the receiver identification information and the encrypted data identification information corresponding to the receiver identification information, so that after receiving the hierarchical encryption information and the encrypted digital currency data, each level of receiver leaves the data it needs and then sends the remaining data to the higher-level receiver, thereby realizing hierarchical encrypted transmission of digital currency data.

[0120] In one embodiment of the present disclosure, the hierarchical encryption information further includes the encryption level and encryption algorithm corresponding to the recipient identification information; in this embodiment, the step of decrypting the encrypted data can be specifically implemented as follows:

[0121] The encrypted data is decrypted according to the encryption level and encryption algorithm corresponding to the recipient identification information.

[0122] As mentioned above, the hierarchical encryption information may also include the encryption level and encryption algorithm corresponding to the recipient identification information. In this way, when the recipient decrypts the encrypted data left behind, the recipient may decrypt the encrypted data left behind according to the encryption level and encryption algorithm corresponding to the corresponding recipient identification information in the hierarchical encryption information.

[0124] Figure 4 A flowchart showing a method for encrypting and transmitting digital currency data according to another embodiment of the present disclosure is shown as follows: Figure 4 As shown, the digital currency data encryption transmission method includes the following steps S401-S403:

[0125] In step S401, the sender obtains the digital currency data to be transmitted; hierarchically encrypts the digital currency data to be transmitted according to the receiver information, wherein the number of receivers is one or more, the receiver information includes receiver identification information, data requirements required by the receiver, and receiver encryption requirements, and the receiver encryption requirements include receiver encryption level requirements and receiver encryption algorithm requirements; generates hierarchical encryption information corresponding to the receiver identification information; sends the hierarchical encryption information and the encrypted digital currency data to the receiver, wherein the hierarchical encryption information includes the receiver identification information and the encrypted data identification information corresponding to the receiver identification information;

[0126] In step S402, the receiver receives the hierarchical encryption information and the encrypted digital currency data sent by the sender; determines the encrypted data required by the receiver from the encrypted digital currency data according to the receiver identification information and the encrypted data identification information corresponding to the receiver identification information; decrypts the encrypted data to obtain the digital currency data required by the receiver; and transparently transmits the hierarchical encryption information corresponding to a higher-level receiver and the encrypted data required by the higher-level receiver to a higher-level receiver according to the receiver identification information and the encrypted data identification information corresponding to the receiver identification information;

[0127] In step S403, a higher-level receiver receives the hierarchical encryption information and encrypted data sent by a lower-level receiver; determines the encrypted data required by the receiver from the encrypted digital currency data based on the receiver identification information and the encrypted data identification information corresponding to the receiver identification information; decrypts the encrypted data to obtain the digital currency data required by the receiver; and transparently transmits the encrypted data required by the higher-level receiver to the higher-level receiver based on the receiver identification information and the encrypted data identification information corresponding to the receiver identification information.

[0128] As mentioned above, with the development of data technology and science and technology, the processing volume of digital currency data is increasing, and in many cases, it is necessary to encrypt and transmit digital currency data to multiple recipients. For example, in the prior art, when a client needs to send certain digital currency data to an acceptance agency, a digital research institute interconnection platform that is higher than the acceptance agency, and a payment collection operation agency that is higher than the digital research institute interconnection platform, the client usually encrypts the digital currency data for the first time and then sends it to the acceptance agency. The acceptance agency decrypts all the received digital currency data, and then encrypts the digital currency data that needs to be uploaded to the higher-level digital research institute interconnection platform and the payment collection operation agency for the second time, and then sends it to the higher-level digital research institute interconnection platform. The digital research institute interconnection platform decrypts all the received digital currency data, and then encrypts the digital currency data that needs to be uploaded to the higher-level payment collection operation agency for the third time, and then sends it to the payment collection operation agency. The problem with this transmission method is that after the low-level receiver decrypts the received encrypted data, it can see all the data required by the high-level receiver, which poses a risk of sensitive information leakage. In addition, since each level of receiver needs to perform encryption before uploading data, this will result in a longer transmission time for the entire data and lower transmission efficiency.

[0129] Considering the above problems, in this embodiment, a method for encrypted transmission of digital currency data is proposed, which performs hierarchical encryption on the digital currency data to be transmitted according to the receiver information, and sends the hierarchical encryption information corresponding to the receiver identification information and the encrypted digital currency data to the receiver. After receiving the hierarchical encryption information and the encrypted digital currency data, the receiver finds the encrypted data corresponding to itself for decryption, and transparently transmits the hierarchical encryption information corresponding to the higher-level receiver and the encrypted data required by the higher-level receiver to the higher-level receiver. This technical solution enables different receivers to obtain the encrypted data they need respectively, thereby avoiding the risk of sensitive information leakage caused by other receivers being able to see the data required by all receivers. At the same time, this technical solution only needs to perform hierarchical encryption once at the sender, instead of the existing technology, where each level of receiver needs to perform encryption operation before uploading data, thereby saving data transmission time and improving data transmission efficiency.

[0130] In one embodiment of the present disclosure, the digital currency data encryption transmission method can be applied to a digital currency data encryption transmission system including a sender and a receiver of computers, electronic devices, etc. that implement digital currency data encryption transmission.

[0132] The following are embodiments of the apparatus of the present disclosure, which can be used to execute embodiments of the method of the present disclosure.

[0133] Figure 5 The structure block diagram of the digital currency data encryption transmission device according to an embodiment of the present disclosure is shown. The device can be implemented as part or all of an electronic device through software, hardware or a combination of both. Figure 5 As shown, the digital currency data encryption transmission device includes:

[0134] The acquisition module 501 is configured to acquire digital currency data to be transmitted;

[0135] The encryption module 502 is configured to perform hierarchical encryption on the digital currency data to be transmitted according to the receiver information, wherein the number of receivers is one or more, the receiver information includes receiver identification information, receiver required data requirements, receiver encryption requirements, and receiver encryption requirements, wherein the receiver encryption requirements include receiver encryption level requirements and receiver encryption algorithm requirements;

[0136] A generating module 503 is configured to generate hierarchical encryption information corresponding to the recipient identification information;

[0137] The sending module 504 is configured to send the hierarchical encryption information and the encrypted digital currency data to the bottom-level receiver.

[0138] As mentioned above, with the development of data technology and science and technology, the processing volume of digital currency data is increasing, and in many cases, it is necessary to encrypt and transmit digital currency data to multiple recipients. For example, in the prior art, when a client needs to send certain digital currency data to an acceptance agency, a digital research institute interconnection platform that is higher than the acceptance agency, and a payment collection operation agency that is higher than the digital research institute interconnection platform, the client usually encrypts the digital currency data for the first time and then sends it to the acceptance agency. The acceptance agency decrypts all the received digital currency data, and then encrypts the digital currency data that needs to be uploaded to the higher-level digital research institute interconnection platform and the payment collection operation agency for the second time, and then sends it to the higher-level digital research institute interconnection platform. The digital research institute interconnection platform decrypts all the received digital currency data, and then encrypts the digital currency data that needs to be uploaded to the higher-level payment collection operation agency for the third time, and then sends it to the payment collection operation agency. The problem with this transmission method is that after the low-level receiver decrypts the received encrypted data, it can see all the data required by the high-level receiver, which poses a risk of sensitive information leakage. In addition, since each level of receiver needs to perform encryption before uploading data, this will result in a longer transmission time for the entire data and lower transmission efficiency.

[0139] In view of the above problems, in this embodiment, a digital currency data encryption transmission device is proposed, which performs hierarchical encryption on the digital currency data to be transmitted according to the receiver information, and sends the hierarchical encryption information corresponding to the receiver identification information and the encrypted digital currency data to the receiver. This technical solution enables different receivers to obtain the encrypted data they need respectively, thereby avoiding the risk of sensitive information leakage caused by other receivers being able to see the data required by all receivers. At the same time, this technical solution only needs to perform hierarchical encryption once on the sender, instead of the existing technology, where each level of receiver needs to perform encryption operation before uploading data, thereby saving data transmission time and improving data transmission efficiency.

[0140] In one embodiment of the present disclosure, the digital currency data encryption transmission device can be implemented as a digital currency data sender such as a computer, electronic device, etc. that performs encrypted transmission of digital currency data.

[0141] In one embodiment of the present disclosure, the digital currency data refers to digital currency data that can be sent, transmitted and processed, such as digital RMB data. More specifically, the digital currency data may be digital RMB transaction data, digital RMB business data, and the like.

[0142] In one embodiment of the present disclosure, the number of the recipients is one or more, for example, the recipient may be an acceptance institution, the next-level recipient of the acceptance institution, the Digital Research Institute Interconnection Platform, and the next-level recipient of the Digital Research Institute Interconnection Platform, the collection operation institution, etc. When the number of the recipients is multiple, the recipient who first receives the digital currency data sent by the digital currency data sender can be considered as the bottom-level recipient, and the recipient who receives the digital currency data last can be considered as the top-level recipient.

[0143] In one embodiment of the present disclosure, the recipient information includes recipient identification information, recipient required data requirements, and recipient encryption requirements, wherein the recipient identification information refers to information used to distinguish the recipient, such as the recipient ID, etc.; the recipient required data requirements refer to data that requires which data the recipient needs, such as the recipient required data requirements can be expressed as the position of the data required by the recipient in the digital currency data to be transmitted, that is, with the help of the recipient required data requirements, it can be understood which data in the digital currency data to be transmitted the data required by the recipient is; the recipient encryption requirements refer to the requirements of the recipient for data encryption, for example, the recipient encryption requirements may include the recipient encryption level requirements and the recipient encryption algorithm requirements, etc.

[0144] In one embodiment of the present disclosure, the hierarchical encryption information refers to the hierarchical encryption information corresponding to the recipient identification information, that is, the hierarchical encryption information can indicate which encrypted data in the encrypted digital currency data is required by which recipient or which level of recipient, and what is the encryption level of the encrypted data and what encryption algorithm is used.

[0145] In the above implementation, the sender first obtains the digital currency data to be transmitted; then, according to the recipient information, the digital currency data to be transmitted is hierarchically encrypted; then, based on the hierarchically encrypted digital currency data, hierarchical encryption information corresponding to the recipient identification information is generated, that is, hierarchical encryption information corresponding to each recipient; finally, the hierarchical encryption information and the encrypted digital currency data are sent to the lowest level recipient, that is, the bottom level recipient.

[0146] In one embodiment of the present disclosure, the encryption module may be configured as follows:

[0147] According to the data requirement of the receiving party, determining the data to be encrypted corresponding to the identification information of the receiving party from the digital currency data to be transmitted;

[0148] The data to be encrypted is encrypted according to the encryption requirement of the receiving party.

[0149] As mentioned above, the recipient information includes recipient identification information, recipient required data requirements and recipient encryption requirements. Therefore, in this embodiment, when the digital currency data to be transmitted is hierarchically encrypted according to the recipient information, first, according to the recipient required data requirements in the recipient information, the data to be encrypted corresponding to the recipient identification information is determined from the digital currency data to be transmitted; then, according to the recipient encryption requirements in the recipient information, the data to be encrypted is encrypted to obtain the digital currency data encrypted for the digital currency data required by different recipients, thereby completing the hierarchical encryption of the digital currency data to be transmitted.

[0150] In one embodiment of the present disclosure, the generating module may be configured as follows:

[0151] Determining encrypted data identification information corresponding to the recipient identification information;

[0152] The receiver identification information and the encrypted data identification information corresponding to the receiver identification information are combined to form hierarchical encryption information corresponding to the receiver identification information.

[0153] In one embodiment of the present disclosure, the encrypted data identification information refers to information used to distinguishably identify a certain part of the encrypted data, such as identification information used to identify the position of a certain part of the encrypted data in the entire encrypted data, etc., that is, based on the encrypted data identification information, the recipient can uniquely determine the encrypted data it needs from the received encrypted data.

[0154] After the digital currency data to be transmitted is hierarchically encrypted according to the recipient information, in order to allow the recipient to uniquely identify the encrypted data part corresponding to it, that is, the part it needs, from the received encrypted digital currency data, in this embodiment, the encrypted data identification information corresponding to the recipient identification information is first determined, that is, the identification of the encrypted data required by different recipients is determined; then the recipient identification information and the encrypted data identification information corresponding to the recipient identification information are combined to form hierarchical encryption information corresponding to the recipient identification information, and the hierarchical encryption information can be subsequently sent to recipients at all levels so that recipients at all levels can accurately obtain the encrypted data they need.

[0155] In one embodiment of the present disclosure, the device may further include:

[0156] The determination module is configured to determine the encryption level and encryption algorithm corresponding to the recipient identification information according to the recipient's encryption requirement.

[0157] In this implementation manner, the receiver identification information and the encrypted data identification information corresponding to the receiver identification information are combined into a part of the hierarchical encryption information corresponding to the receiver identification information, which is specifically configured as follows:

[0158] The receiver identification information and the encrypted data identification information, encryption level and encryption algorithm corresponding to the receiver identification information are combined to form hierarchical encryption information corresponding to the receiver identification information.

[0159] As mentioned above, the recipient information includes recipient identification information, data requirements required by the recipient and recipient encryption requirements. In this embodiment, the encryption level and encryption algorithm corresponding to the recipient identification information can also be determined according to the recipient encryption requirements in the recipient information, that is, the encryption levels and encryption algorithms required by different recipients. In this way, the encryption levels and encryption algorithms required by different recipients can also be put into the hierarchical encryption information, that is, the recipient identification information and the encrypted data identification information, encryption level and encryption algorithm corresponding to the recipient identification information are combined to form the hierarchical encryption information corresponding to the recipient identification information and sent to the recipient, so that the recipient can not only accurately determine what encrypted data he needs, but also accurately understand the encryption level of these encrypted data and the encryption algorithms used.

[0160] Figure 6 The following is a block diagram showing a digital currency data encryption transmission device according to another embodiment of the present disclosure. The device can be implemented as part or all of an electronic device through software, hardware, or a combination of both. Figure 6 As shown, the digital currency data encryption transmission device includes:

[0161] The first receiving module 601 is configured to receive hierarchical encryption information and encrypted digital currency data sent by a sender, wherein the hierarchical encryption information includes receiver identification information and encrypted data identification information corresponding to the receiver identification information;

[0162] A first determination module 602 is configured to determine the encrypted data required by the recipient from the encrypted digital currency data according to the recipient identification information and the encrypted data identification information corresponding to the recipient identification information;

[0163] The first decryption module 603 is configured to decrypt the encrypted data to obtain the digital currency data required by the recipient;

[0164] The first transparent transmission module 604 is configured to transparently transmit the hierarchical encryption information corresponding to the higher-level receiver and the encrypted data required by the higher-level receiver to the higher-level receiver according to the receiver identification information and the encrypted data identification information corresponding to the receiver identification information.

[0165] As mentioned above, with the development of data technology and science and technology, the processing volume of digital currency data is increasing, and in many cases, it is necessary to encrypt and transmit digital currency data to multiple recipients. For example, in the prior art, when a client needs to send certain digital currency data to an acceptance agency, a digital research institute interconnection platform that is higher than the acceptance agency, and a payment collection operation agency that is higher than the digital research institute interconnection platform, the client usually encrypts the digital currency data for the first time and then sends it to the acceptance agency. The acceptance agency decrypts all the received digital currency data, and then encrypts the digital currency data that needs to be uploaded to the higher-level digital research institute interconnection platform and the payment collection operation agency for the second time, and then sends it to the higher-level digital research institute interconnection platform. The digital research institute interconnection platform decrypts all the received digital currency data, and then encrypts the digital currency data that needs to be uploaded to the higher-level payment collection operation agency for the third time, and then sends it to the payment collection operation agency. The problem with this transmission method is that after the low-level receiver decrypts the received encrypted data, it can see all the data required by the high-level receiver, which poses a risk of sensitive information leakage. In addition, since each level of receiver needs to perform encryption before uploading data, this will result in a longer transmission time for the entire data and lower transmission efficiency.

[0166] Considering the above problems, in this embodiment, a digital currency data encryption transmission device is proposed, which performs hierarchical encryption on the digital currency data to be transmitted according to the receiver information, and sends the hierarchical encryption information corresponding to the receiver identification information and the encrypted digital currency data to the receiver. After receiving the hierarchical encryption information and the encrypted digital currency data, the receiver finds the encrypted data corresponding to itself for decryption, and transparently transmits the hierarchical encryption information corresponding to the higher-level receiver and the encrypted data required by the higher-level receiver to the higher-level receiver. This technical solution enables different receivers to obtain the encrypted data they need respectively, thereby avoiding the risk of sensitive information leakage caused by other receivers being able to see the data required by all receivers. At the same time, this technical solution only needs to perform hierarchical encryption once at the sender, instead of the existing technology, where each level of receiver needs to perform encryption operations before uploading data, thereby saving data transmission time and improving data transmission efficiency.

[0167] In one embodiment of the present disclosure, the digital currency data encryption transmission device can be implemented as a digital currency data receiver such as a computer, electronic device, etc. that implements digital currency data encryption transmission, especially a low-level receiver.

[0168] In this embodiment, the bottom-level receiver first receives all the hierarchical encryption information and encrypted digital currency data sent by the sender, wherein the hierarchical encryption information includes receiver identification information and encrypted data identification information corresponding to the receiver identification information; then the bottom-level receiver finds the encrypted data required by the bottom-level receiver from the encrypted digital currency data according to the receiver identification information and the encrypted data identification information corresponding to the receiver identification information; then the bottom-level receiver decrypts the encrypted data to obtain the digital currency data required by the bottom-level receiver; finally, the bottom-level receiver transparently transmits the hierarchical encryption information corresponding to the higher-level receiver and the encrypted data required by the higher-level receiver to the higher-level receiver according to the receiver identification information and the encrypted data identification information corresponding to the receiver identification information, wherein the hierarchical encryption information corresponding to the higher-level receiver and the encrypted data required by the higher-level receiver include not only the hierarchical encryption information corresponding to the receiver one level higher than the bottom-level receiver and the encrypted data required by the receiver, but also the hierarchical encryption information corresponding to other receivers higher than the bottom-level receiver and the encrypted data required by these receivers. That is to say, after the bottom-level receiver receives all the hierarchical encrypted information and encrypted digital currency data sent by the sender, the receiver leaves the data it needs and then transparently transmits the hierarchical encrypted information and encrypted digital currency data needed by the higher-level receiver to the receiver at the next higher level. After the receiver at the next higher level than the bottom-level receiver receives the hierarchical encrypted information and encrypted digital currency data sent by the bottom-level receiver, the receiver leaves the data it needs and then transparently transmits the hierarchical encrypted information and encrypted digital currency data needed by the higher-level receiver to the receiver at the next higher level, similar to the bottom-level receiver. Similarly, after receiving the hierarchical encrypted information and encrypted digital currency data, the receiver at each level leaves the data it needs and then sends the remaining data to the higher-level receiver to realize the hierarchical encrypted transmission of digital currency data.

[0169] In one embodiment of the present disclosure, the hierarchical encryption information further includes an encryption level and an encryption algorithm corresponding to the recipient identification information; in this embodiment, the first decryption module is specifically configured as follows:

[0170] The encrypted data is decrypted according to the encryption level and encryption algorithm corresponding to the recipient identification information.

[0171] As mentioned above, the hierarchical encryption information may also include the encryption level and encryption algorithm corresponding to the recipient identification information. In this way, when the recipient decrypts the encrypted data left behind, the recipient may decrypt the encrypted data left behind according to the encryption level and encryption algorithm corresponding to the corresponding recipient identification information in the hierarchical encryption information.

[0173] Figure 7 The following is a block diagram showing a digital currency data encryption transmission device according to another embodiment of the present disclosure. The device can be implemented as part or all of an electronic device through software, hardware, or a combination of both. Figure 7 As shown, the digital currency data encryption transmission device includes:

[0174] The second receiving module 701 is configured to receive hierarchical encryption information and encrypted data sent by a lower-level receiver, wherein the hierarchical encryption information includes receiver identification information and encrypted data identification information corresponding to the receiver identification information;

[0175] The second determination module 702 is configured to determine the encrypted data required by the recipient from the encrypted digital currency data according to the recipient identification information and the encrypted data identification information corresponding to the recipient identification information;

[0176] The second decryption module 703 is configured to decrypt the encrypted data to obtain the digital currency data required by the recipient;

[0177] The second transparent transmission module 704 is configured to transparently transmit the encrypted data required by the higher-level receiver to the higher-level receiver according to the receiver identification information and the encrypted data identification information corresponding to the receiver identification information.

[0178] As mentioned above, with the development of data technology and science and technology, the processing volume of digital currency data is increasing, and in many cases, it is necessary to encrypt and transmit digital currency data to multiple recipients.

The acceptance agency decrypts all the received digital currency data, and then encrypts the digital currency data that needs to be uploaded to the higher-level digital research institute interconnection platform and the payment collection operation agency for the second time, and then sends it to the higher-level digital research institute interconnection platform. The digital research institute interconnection platform decrypts all the received digital currency data, and then encrypts the digital currency data that needs to be uploaded to the higher-level payment collection operation agency for the third time, and then sends it to the payment collection operation agency. The problem with this transmission method is that after the low-level receiver decrypts the received encrypted data, it can see all the data required by the high-level receiver, which poses a risk of sensitive information leakage. In addition, since each level of receiver needs to perform encryption before uploading data, this will result in a longer transmission time for the entire data and lower transmission efficiency.

At the same time, this technical solution only needs to perform hierarchical encryption once at the sender, instead of the existing technology, where each level of receiver needs to perform encryption operations before uploading data, thereby saving data transmission time and improving data transmission efficiency.

[0180] In one embodiment of the present disclosure, the digital currency data encryption transmission device can be implemented as a digital currency data receiver such as a computer, electronic device, etc. that implements digital currency data encryption transmission, especially a high-level receiver at the next level of the low-level receiver.

[0181] In this embodiment, a high-level receiver receives hierarchical encryption information and encrypted data sent by a low-level receiver, wherein the hierarchical encryption information includes receiver identification information and encrypted data identification information corresponding to the receiver identification information; then the high-level receiver finds the encrypted data required by the high-level receiver from the encrypted digital currency data according to the receiver identification information and the encrypted data identification information corresponding to the receiver identification information; then the high-level receiver decrypts the encrypted data to obtain the digital currency data required by the high-level receiver; finally, the high-level receiver transmits the hierarchical encryption information corresponding to the higher-level receiver and the encrypted data required by the higher-level receiver to the higher-level receiver according to the receiver identification information and the encrypted data identification information corresponding to the receiver identification information, so that after receiving the hierarchical encryption information and the encrypted digital currency data, each level of receiver leaves the data it needs and then sends the remaining data to the higher-level receiver, thereby realizing hierarchical encrypted transmission of digital currency data.

[0182] In one embodiment of the present disclosure, the hierarchical encryption information further includes an encryption level and an encryption algorithm corresponding to the recipient identification information; in this embodiment, the second decryption module is specifically configured as follows:

[0183] The encrypted data is decrypted according to the encryption level and encryption algorithm corresponding to the recipient identification information.

[0184] As mentioned above, the hierarchical encryption information may also include the encryption level and encryption algorithm corresponding to the recipient identification information. In this way, when the recipient decrypts the encrypted data left behind, the recipient may decrypt the encrypted data left behind according to the encryption level and encryption algorithm corresponding to the corresponding recipient identification information in the hierarchical encryption information.

[0186] Figure 8 The structure block diagram of the digital currency data encryption transmission system according to an embodiment of the present disclosure is shown. The system can be implemented as part or all of an electronic device through software, hardware or a combination of both. Figure 8 As shown, the digital currency data encryption transmission system includes:

[0190] As mentioned above, with the development of data technology and science and technology, the processing volume of digital currency data is increasing, and in many cases, it is necessary to encrypt and transmit digital currency data to multiple recipients.

The acceptance agency decrypts all the received digital currency data, and then encrypts the digital currency data that needs to be uploaded to the higher-level digital research institute interconnection platform and the payment collection operation agency for the second time, and then sends it to the higher-level digital research institute interconnection platform. The digital research institute interconnection platform decrypts all the received digital currency data, and then encrypts the digital currency data that needs to be uploaded to the higher-level payment collection operation agency for the third time, and then sends it to the payment collection operation agency. The problem with this transmission method is that after the low-level receiver decrypts the received encrypted data, it can see all the data required by the high-level receiver, which poses a risk of sensitive information leakage. In addition, since each level of receiver needs to perform encryption before uploading data, this will result in a longer transmission time for the entire data and lower transmission efficiency.

[0191] Considering the above problems, in this embodiment, a digital currency data encryption transmission system is proposed, which performs hierarchical encryption on the digital currency data to be transmitted according to the receiver information, and sends the hierarchical encryption information corresponding to the receiver identification information and the encrypted digital currency data to the receiver. After receiving the hierarchical encryption information and the encrypted digital currency data, the receiver finds the encrypted data corresponding to itself for decryption, and transparently transmits the hierarchical encryption information corresponding to the higher-level receiver and the encrypted data required by the higher-level receiver to the higher-level receiver. This technical solution enables different receivers to obtain the encrypted data they need respectively, thereby avoiding the risk of sensitive information leakage caused by other receivers being able to see the data required by all receivers. At the same time, this technical solution only needs to perform hierarchical encryption once at the sender, instead of the existing technology, where each level of receiver needs to perform encryption operations before uploading data, thereby saving data transmission time and improving data transmission efficiency.

[0192] In one embodiment of the present disclosure, the digital currency data encryption transmission system can be implemented as a digital currency data encryption transmission system including a sender and a receiver, including a computer, an electronic device, etc. that implements digital currency data encryption transmission.
