[0066] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Based on the embodiments of the present application, all other embodiments made by those of ordinary skill in the art under the inspiration of this embodiment belong to the scope of protection of the present application.

[0067] In the description and claims of this application and the above-mentioned drawings, terms such as "first", "second", "third", "fourth", etc. (if any) are used to distinguish similar objects and do not necessarily describe a specific order or sequence. It should be understood that such data used can be interchanged under appropriate circumstances so that the embodiments of this application described here can be implemented in an order other than those illustrated or described here. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products, or devices.

[0068] With the development of technology, various data are increasing day by day, and all walks of life attach more and more importance to the security of data. For data transmission, it is also necessary to encrypt the data before transmission.

[0069] In the prior art, for the encrypted transmission of data, usually the sending device uses a key and an encryption / decryption algorithm to encrypt the original data, obtains the encrypted data and transmits it to the receiving device. The receiving device uses the same encryption / decryption algorithm and key to decrypt the encrypted data to obtain the original data. Due to the use of a fixed encryption / decryption algorithm and key, there will be a problem of low security in data transmission.

[0070] In view of the problems existing in the prior art, the inventors found in the process of researching the data encryption transmission method that in order to improve the security of data transmission, the sending device can randomly select a key and an encryption / decryption algorithm for encryption, and then transmit the encrypted data and the target marking information that can determine the key and the encryption / decryption algorithm to the receiving device. Then the receiving device determines the key and the encryption / decryption algorithm according to the received target marking information for decryption, which can effectively improve the security of data transmission. Based on the above inventive concept, the data encryption transmission solution in this application is designed.

[0071] In this application, the sending device and the receiving device can be terminal devices, gateways, servers, etc. The embodiments of this application do not limit them and can be determined according to the actual situation.

[0072] Exemplarily, Figure 1 is a schematic diagram of the application scenario of the data encryption transmission method provided by this application. As Figure 1 shown, in this application scenario, there are multiple sending devices, namely smart communication terminals, tablet computers, and smart watches, and the receiving device is a gateway. Hereinafter, an example of a smart communication terminal sending data to the gateway will be used for illustration.

[0073] Before the intelligent communication terminal sends data to the gateway, the intelligent communication terminal interacts with the gateway so that both the intelligent communication terminal and the gateway obtain the same marking information, multiple keys, and multiple encryption and decryption algorithms.

[0074] Furthermore, for each key and each encryption and decryption algorithm, the intelligent communication terminal and the gateway use the key and the encryption and decryption algorithm to encrypt the marking information to obtain the encrypted marking information; then, after establishing a correspondence between the encrypted marking information, the key, and the encryption and decryption algorithm, they store it.

[0075] When the intelligent communication terminal needs to send data to the gateway, it first randomly selects the target marking information from multiple encrypted marking information.

[0076] Furthermore, it uses the target key and the target encryption and decryption algorithm corresponding to the target marking information to encrypt the original data to obtain the encrypted data; then it sends the target data to the receiving device, where the target data includes the encrypted data and the target marking information.

[0077] After receiving the target data, the gateway determines the target key and the target encryption and decryption algorithm corresponding to the target marking information according to the correspondence between the encrypted marking information, the key, and the encryption and decryption algorithm.

[0078] Then it uses the target key and the target encryption and decryption algorithm to decrypt the encrypted data to obtain the original data, thus completing the data transmission process.

[0079] It should be noted that Figure 1 This is only a schematic diagram of an application scenario provided by the embodiments of the present application. The embodiments of the present application do not limit Figure 1 the actual forms of various devices included, nor do they limit Figure 1 the interaction methods between the devices. In the specific application of the solution, it can be set according to actual needs.

[0080] Next, the technical solution of the present application will be described in detail through specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0081] Figure 2 This is a schematic flowchart of the first embodiment of the data encryption and transmission method provided by the present application. The embodiments of the present application illustrate the situation where the sending device randomly selects the target marking information from multiple encrypted marking information, and then uses the target key and the target encryption and decryption algorithm corresponding to the target marking information to encrypt the original data. The receiving device uses the target key and the target encryption and decryption algorithm corresponding to the determined target marking information to decrypt the encrypted data. The method in this embodiment can be implemented through software, hardware, or a combination of software and hardware. For example Figure 2As shown, the data encryption and transmission method specifically includes the following steps:

[0082] S201: The sending device randomly selects a target marker information from multiple encrypted marker information.

[0083] In this step, when the sending device needs to send data to the receiving device, in order to improve the security of data transmission, it first randomly selects the target marker information from the multiple stored encrypted marker information.

[0084] Among them, the multiple encrypted marker information is the information obtained by encrypting the marker information respectively using multiple groups of keys and encryption and decryption algorithms.

[0085] S202: The sending device encrypts the original data using the target key and target encryption and decryption algorithm corresponding to the target marker information to obtain encrypted data.

[0086] In this step, after the sending device obtains the target marker information, because the corresponding relationship between the encrypted marker information and the key and encryption and decryption algorithm is stored in the sending device, it can determine the target key and target encryption and decryption algorithm corresponding to the target marker information. Furthermore, the sending device encrypts the original data using the target key and target encryption and decryption algorithm corresponding to the target marker information to obtain encrypted data.

[0087] S203: The sending device sends the target data to the receiving device.

[0088] In this step, after the sending device obtains the encrypted data, it can perform data transmission and send the target data to the receiving device. The target data includes the encrypted data and the target marker information.

[0089] S204: After the receiving device receives the target data sent by the sending device, it determines the target key and target encryption and decryption algorithm corresponding to the target marker information according to the corresponding relationship between the encrypted marker information and the key and encryption and decryption algorithm.

[0090] In this step, after the sending device sends the target data to the receiving device, the receiving device can receive the target data. Since the corresponding relationship between the encrypted marker information and the key and encryption and decryption algorithm is stored in the receiving device, it can determine the target key and target encryption and decryption algorithm corresponding to the target marker information in the target data.

[0091] It should be noted that the sending device can place the target marker information at a preset position of the encrypted data. The receiving device can read the data at the preset position to obtain the target marker information, and the remaining data is the encrypted data. The preset position can be the starting position, the ending position, the middle position, etc. The embodiments of the present application do not limit the preset position and can be determined according to the actual situation.

[0092] S205: The receiving device decrypts the encrypted data using the target key and the target encryption / decryption algorithm to obtain the original data.

[0093] In this step, after the receiving device determines the target key and the target encryption / decryption algorithm corresponding to the target marking information, it can use the target key and the target encryption / decryption algorithm to decrypt the encrypted data in the target data to obtain the original data, thus completing the data transmission process.

[0094] The data encryption and transmission method provided in this embodiment enables the sending device to randomly select target marking information from multiple encrypted marking information, and then uses the target key and the target encryption / decryption algorithm corresponding to the target marking information to encrypt the original data to obtain encrypted data, and then sends the encrypted data and the target marking information to the receiving device. The receiving device uses the target key and the target encryption / decryption algorithm corresponding to the determined target marking information to decrypt the encrypted data to obtain the original data. Compared with the prior art where a fixed encryption / decryption algorithm and key are used for encryption and decryption, this solution effectively improves the security of data transmission by encrypting and decrypting using the target key and the target encryption / decryption algorithm corresponding to the randomly selected target marking information each time.

[0095] Figure 3 It is a schematic flowchart of the second embodiment of the data encryption and transmission method provided in this application. On the basis of the above embodiment, this embodiment of the application describes the situation where the sending device and the receiving device obtain keys, encryption / decryption algorithms, marking information, and generate the corresponding relationship between the encrypted marking information and the keys and encryption / decryption algorithms. As Figure 3 shown, the data encryption and transmission method specifically includes the following steps:

[0096] S301: The sending device and the receiving device interact to obtain marking information, multiple keys, and multiple encryption / decryption algorithms.

[0097] Before data transmission, to ensure the security during the data transmission process, the sending device and the receiving device need to obtain keys, encryption / decryption algorithms, marking information, and generate the corresponding relationship between the encrypted marking information and the keys and encryption / decryption algorithms.

[0098] In this step, the sending device and the receiving device interact, and the sending device and the receiving device obtain the same marking information, multiple keys, and multiple encryption / decryption algorithms.

[0099] S302: For each key and each encryption / decryption algorithm, the sending device and the receiving device use the key and the encryption / decryption algorithm to encrypt the marking information to obtain the encrypted marking information.

[0100] In this step, after the sender device and the receiver device obtain the same tag information, multiple keys, and multiple encryption and decryption algorithms, for each key and each encryption and decryption algorithm, the sender device and the receiver device use the key and the encryption and decryption algorithm to encrypt the tag information to obtain the encrypted tag information. The key and the encryption and decryption algorithm form a set of data.

[0101] Exemplarily, two keys are obtained, namely key A and key B; three encryption and decryption algorithms are obtained, namely algorithm 1, algorithm 2, and algorithm 3; six encrypted tag information can be obtained, which are: the encrypted tag information obtained by encrypting the tag information with key A and algorithm 1, the encrypted tag information obtained by encrypting the tag information with key A and algorithm 2, the encrypted tag information obtained by encrypting the tag information with key A and algorithm 3, the encrypted tag information obtained by encrypting the tag information with key B and algorithm 1, the encrypted tag information obtained by encrypting the tag information with key B and algorithm 2, and the encrypted tag information obtained by encrypting the tag information with key B and algorithm 3.

[0102] S303: After the sender device and the receiver device establish a corresponding relationship between the encrypted tag information, the key, and the encryption and decryption algorithm, they store it.

[0103] In this step, after the sender device and the receiver device obtain the encrypted tag information, they establish a corresponding relationship between the encrypted tag information, the key, and the encryption and decryption algorithm and then store it for use in subsequent data transmission processes.

[0104] It should be noted that when at least one of the multiple encryption and decryption algorithms is discarded, the steps in this embodiment can be re-executed.

[0105] The data encryption and transmission method provided in this embodiment encrypts the obtained tag information by the sender device and the receiver device according to the obtained multiple keys and multiple encryption and decryption algorithms, and then stores the encrypted tag information after establishing a corresponding relationship with the key and the encryption and decryption algorithm, so that random selection can be made from multiple keys and multiple encryption and decryption algorithms during data transmission, improving the security of data transmission.

[0106] Figure 4 It is a schematic flowchart of the third embodiment of the data encryption and transmission method provided in this application. On the basis of the above embodiment, this application embodiment describes the situation where the sender device and the receiver device interact to obtain tag information, multiple keys, and multiple encryption and decryption algorithms. As Figure 4 shown, the data encryption and transmission method specifically includes the following steps:

[0107] S401: The sender device sends an encryption parameter negotiation request to the receiver device.

[0108] In this step, in order to obtain the marking information, multiple keys, and multiple encryption and decryption algorithms, the sender device needs to send an encryption parameter negotiation request to the receiver device. The encryption parameter negotiation request includes multiple encryption and decryption algorithms to be selected. The encryption and decryption algorithms to be selected are algorithms that the sender device can implement.

[0109] It should be noted that the encryption and decryption algorithms to be selected can be the Data Encryption Standard (DES) algorithm, the Advanced Encryption Standard (AES) algorithm, the SM4 algorithm, etc. The embodiments of the present application do not limit the encryption and decryption algorithms to be selected, and can be determined according to the actual situation.

[0110] S402: After the receiver device receives the encryption parameter negotiation request sent by the sender device, select multiple encryption and decryption algorithms from the multiple encryption and decryption algorithms to be selected.

[0111] In this step, after the sender device sends the encryption parameter negotiation request to the receiver device, the receiver device can receive the request, and then select the algorithms that it can implement from the multiple encryption and decryption algorithms to be selected in the request to obtain multiple encryption and decryption algorithms.

[0112] S403: The receiver device generates the marking information.

[0113] In the step, after the receiver device receives the encryption parameter negotiation request, it can generate the marking information.

[0114] It should be noted that the marking information can be an encrypted information such as a randomly generated string, a randomly generated number, a randomly generated text, etc. The embodiments of the present application do not limit the marking information and can be determined according to the actual situation.

[0115] It should be noted that the execution order of the receiver device to determine multiple encryption and decryption algorithms and generate the marking information can be: first determine multiple encryption and decryption algorithms, and then generate the marking information; it can also be: first determine and generate the marking information, and then execute multiple encryption and decryption algorithms; it can also be: determine multiple encryption and decryption algorithms and generate the marking information at the same time. The embodiments of the present application do not limit the execution order of the receiver device to determine multiple encryption and decryption algorithms and generate the marking information, and can be determined according to the actual situation.

[0116] S404: The receiver device sends the marking information and multiple encryption and decryption algorithms to the sender device.

[0117] In this step, after the receiving device obtains the marking information and multiple encryption and decryption algorithms, it sends them to the sending device for subsequent storage by the sending device.

[0118] S405: After the sending device receives the marking information and multiple encryption and decryption algorithms sent by the receiving device, it sends multiple first key data to the receiving device.

[0119] In this step, after the receiving device sends the marking information and multiple encryption and decryption algorithms to the sending device, the sending device can receive and store the marking information and multiple encryption and decryption algorithms, and then send multiple first key data to the receiving device. The first key data can be a randomly generated string.

[0120] S406: After the receiving device receives the multiple first key data sent by the sending device, it sends the second key data corresponding to each first key data to the sending device.

[0121] In this step, after the sending device sends multiple first key data to the receiving device, the receiving device can receive the multiple first key data, and then for each first key data, generate the corresponding second key data and send it to the sending device. The second key data can be a randomly generated string.

[0122] S407: For each first key data, the receiving device generates a key based on the first key data and the second key data corresponding to the first key data.

[0123] In this step, after the receiving device generates the second key data corresponding to each first key data, for each first key data, it uses a key generation algorithm to generate and store a key based on the first key data and the second key data corresponding to the first key data.

[0124] S408: After the sending device receives the second key data corresponding to each first key data sent by the receiving device, for each first key data, it generates a key based on the first key data and the second key data corresponding to the first key data.

[0125] In this step, after the receiving device sends the second key data corresponding to each first key data to the sending device, the sending device can receive the second key data, and then for each first key data, it uses a key generation algorithm to generate and store a key based on the first key data and the second key data corresponding to the first key data.

[0126] It should be noted that the execution steps of the sending device and the receiving device can be interchanged.

[0127] The data encryption and transmission method provided in this embodiment enables the sender device to send the algorithms it can implement to the receiver device. The receiver device selects the algorithms it can implement from them as multiple encryption and decryption algorithms, ensuring that both the sender device and the receiver device can use encryption and decryption algorithms. By the sender device determining the first key data and the receiver device determining the second key data, the key is made more complex, improving the security of data transmission.
