[0032] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0033] The cloud terminal is lightweight, thin and transparent. In use, the cloud terminal does not perform computing and storage. The heavy computing tasks such as computing, storage and control are placed on the cloud server for processing. The system and data displayed by the cloud terminal are determined by the cloud server. The cloud terminal only plays a role of connection and display. After the cloud terminal is connected to the cloud server through the protocol, it can achieve the same use effect as the physical terminal and meet the various needs of users.

[0034] The communication between the cloud terminal and the cloud requires the participation of the network. When data is transmitted through the network, there is a lack of security protection measures. Data can be maliciously intercepted, resulting in property loss and privacy information leakage of cloud terminal users. In serious cases, the cloud terminal is in dangerous operation.

[0035] Therefore, the present disclosure provides a data transmission method, which implements hardware-level encryption at the cloud terminal when the cloud terminal transmits data to the cloud server, thereby ensuring data transmission security.

[0036] Figure 1 is a schematic diagram of a cloud terminal encryption system according to an exemplary embodiment of the present disclosure, referring to Figure 1 As shown, the cloud terminal and the cloud server establish communication through network communication or mobile communication network to perform data transmission. Among them, the data transmission of the cloud terminal involves multiple hardware entities, including hardware entities corresponding to the transmission steps such as information source, encoding, modulation, frequency conversion, and transmission. The data transmission of the cloud server involves multiple hardware entities, including hardware entities corresponding to the steps of receiving, frequency conversion, demodulation, and decoding, and finally obtains the information transmitted by the cloud server.

[0037] Figure 2is a flowchart of a data transmission method according to an exemplary embodiment of the present disclosure, which is applied to a cloud terminal, such as Figure 2 As shown, the data transmission method includes the following steps.

[0038] In step S101, the data encryption type of data transmitted from the cloud terminal to the cloud server is determined, where the data encryption type is used to indicate an encryption hardware entity that encrypts the data.

[0039] In step S102, the encryption hardware entity encrypts the data based on the data encryption type indication, and transmits the encrypted data to the cloud server.

[0040] In an embodiment of the present disclosure, a cloud terminal transmits data to a cloud server, and the data transmission involves multiple hardware entities at the cloud terminal. For example, the steps of source, encoding, modulation, frequency conversion, and transmission in the data transmission process involve hardware entities such as clock circuits, source receivers, encoders, and modulators. Among the multiple hardware entities that transmit data between the cloud terminal and the cloud server, at least one hardware entity is randomly selected as an encryption hardware entity. The data is encrypted using the encryption hardware entity, and the data encryption type used to indicate the encryption hardware entity for encrypting the data is determined, and the encryption hardware entity is determined based on the data encryption type. The data is encrypted based on the encryption hardware entity, and the encrypted data is transmitted to the cloud server.

[0041] According to the embodiments of the present disclosure, by determining the encryption hardware entity used to encrypt data based on the data encryption type in the hardware entity that transmits data between the cloud terminal and the cloud server, encrypting the data based on the encryption hardware entity, and transmitting the encrypted data to the cloud server, encryption is performed using encryption hardware when the cloud terminal transmits data to the cloud server, thereby achieving hardware-level encryption and ensuring safe data use.

[0042] In one embodiment, the cloud terminal and the cloud server have an encryption and decryption mechanism and secret key set in a peer-to-peer manner. When the cloud terminal communicates with the cloud server, the cloud terminal data is encoded and encrypted. Among the multiple hardware entities that transmit data between the cloud terminal and the cloud server, at least one hardware entity is randomly selected as an encryption hardware entity. Certain bits of information in the transmitted data include the data encryption type. The cloud server receives the encrypted data of the cloud terminal, determines the data encryption type of the cloud terminal based on the encrypted bit information, and the cloud calls the decryption key from the secret key library to decrypt the received data.

[0043] In one embodiment, the cloud terminal data is encrypted after being encoded, and at least one hardware entity is randomly selected from multiple hardware entities that transmit data between the cloud terminal and the cloud server as an encryption hardware entity. The cloud terminal randomly encodes the secret key in the data during encryption, and transmits the encrypted data to the cloud server. The cloud server receives the encrypted data from the cloud terminal and decrypts the received data based on the corresponding decryption key.

[0044] In one embodiment, when a cloud terminal transmits data to a cloud server, encryption hardware is used in the cloud terminal to encrypt data, an encryption hardware entity is determined based on the data encryption type, and data is encrypted based on the encryption hardware entity, and a microcontroller unit of the terminal controls the data transmission process. The microcontroller unit randomly selects a hardware entity as an encryption hardware entity, and information such as the data encryption type of the data transmission can be an encryption vector, included in the transmission data, and transmitted to the cloud server. The cloud server has a corresponding decryption vector, and the elements in the decryption vector contain encryption items, and the encryption matrix corresponds to each other in the cloud terminal and the cloud server. The encrypted matrix can perform operations similar to matrix operations and inverse operations of the matrix to realize dynamic encryption of the data transmission process, protect the user's data security, and realize physical layer hardware-level encryption when data is transmitted between the cloud terminal and the cloud server.

[0045] Figure 3 is a flowchart of a method for encrypting data by an encryption hardware entity based on a data encryption type indication according to an exemplary embodiment of the present disclosure, such as Figure 3 As shown, the method includes the following steps.

[0046] In step S201, if the encryption hardware entity includes a clock circuit, a clock signal generated by the clock circuit and data transmitted in the hardware entity controlled by the clock signal are determined.

[0047] In step S202, the data transmitted in the hardware entity controlled by the clock signal is encrypted by adjusting the correspondence between the clock signal and the number of data bits transmitted in the hardware entity.

[0048] In one embodiment of the present disclosure, the cloud terminal transmits data to the cloud server, and the data is encrypted by the hardware entity. Among the multiple hardware entities that transmit data between the cloud terminal and the cloud server, at least one hardware entity is randomly selected as the encryption hardware entity. It can be understood that among the multiple hardware entities that transmit data between the cloud terminal and the cloud server, multiple hardware entities are selected as encryption hardware entities. The multiple encryption entities can be used as encryption entities corresponding to different stages of data transmission, and the superposition effect is used to jointly realize encryption. The encryption hardware entity is determined based on the data encryption type. If the encryption hardware entity includes a clock circuit, the clock signal generated by the clock circuit and the data transmitted in the hardware entity controlled by the clock signal are determined. When the cloud terminal processes the signal, the work of each part of the hardware entity is carried out according to the beat. To make the parts of the circuit unify the beat, a clock signal is required. The circuit that generates the clock signal is the clock circuit. When it is determined that the encryption hardware entity includes a clock circuit, the clock signal generated by the clock circuit and the data transmitted in the hardware entity controlled by the clock signal are determined. The clock signal represents a special signal oscillation between high and low states. The use of the signal is like a digital circuit that coordinates the action of a metronome. The clock signal can be a square wave voltage with a low level and a high level. The hardware entity controlled by the clock signal may be a source receiver, an encoder, a modulator, a frequency converter, etc., that is, the data transmitted in the source receiver is encrypted by the clock signal generated by the clock circuit, the data transmitted in the encoder is encrypted by the clock signal generated by the clock circuit, or the data transmitted in the modulator is encrypted by the clock signal generated by the clock circuit. When encrypting the data transmitted in the hardware entity controlled by the clock signal, it is achieved by adjusting the corresponding relationship between the clock signal and the number of data bits transmitted in the hardware entity. The corresponding relationship between the clock signal and the number of data bits transmitted in the hardware entity is that one clock signal transmits one bit of data, or one clock signal transmits multiple bits of data, or multiple clock signals transmit one bit of data, etc. When encrypting the data transmitted in the hardware entity controlled by the clock signal, the data transmitted in one or more hardware entities may be encrypted. When encrypting the data transmitted in multiple hardware entities, the corresponding relationship between the same clock signal and the number of data bits transmitted in the hardware entity may be adopted, or different corresponding relationships may be adopted. For example, the data transmitted by the source receiver is encrypted by using the clock circuit, and one clock signal transmits a first value of bits of data. For another example, the clock circuit is used to encrypt data transmitted by the source receiver, and the data transmitted by the modulator is encrypted at the same time, and the second value number of bits of data are transmitted for one clock signal.For another example, a clock circuit is used to encrypt data transmitted by a source receiver, and at the same time, data transmitted by an encoder is encrypted. The data transmitted by the source receiver is encrypted by using a clock signal to transmit data of a third numerical value of bits, and the data transmitted by the encoder is encrypted by using a clock signal to transmit data of a fourth numerical value of bits.

[0049] Figure 4 is a schematic diagram of a cloud terminal encryption circuit according to an exemplary embodiment of the present disclosure, referring to Figure 4 The encryption hardware entity includes a clock circuit, which encrypts data transmitted in the hardware entity controlled by the clock signal. The hardware entity controlled by the clock signal includes one or more of a source receiver, an encoder, a modulator and a frequency converter.

[0050] When encrypting, under the control of the microcontroller unit of the cloud terminal, the clock signal generated by the clock circuit and the data transmitted in the hardware entity controlled by the clock signal are determined, and the correspondence between the clock signal and the number of data bits transmitted in the hardware entity is adjusted. The correspondence includes one clock signal transmitting one or more bits of data, etc.

[0051] According to the embodiments of the present disclosure, a clock signal is generated by using a clock circuit in a hardware entity that transmits data between a cloud terminal and a cloud server, and data transmitted in hardware entities such as a source receiver, encoder, modulator, and frequency converter controlled by the clock signal are encrypted. The data is encrypted based on the encryption hardware entity, and the encrypted data is transmitted to the cloud server, thereby achieving hardware-level encryption when the cloud terminal transmits data to the cloud server, thereby ensuring safe data use.

[0052] Figure 5 is a flowchart of a method for encrypting data by an encryption hardware entity based on a data encryption type indication according to an exemplary embodiment of the present disclosure, such as Figure 5 As shown, the method includes the following steps.

[0053] In step S301, if the encryption hardware entity includes a source receiver and an encoder, a source signal received by the source receiver is determined.

[0054] In step S302, during the source coding process, the source signal is encoded and encrypted by adjusting at least one of the data level, the transition of the signal edge, the rising edge and the falling edge, the physical information represented by the bit, and the bit compression information.

[0055] In the disclosed embodiment, the cloud terminal transmits data to the cloud server, and the data is encrypted by a hardware entity. Among the multiple hardware entities that transmit data between the cloud terminal and the cloud server, at least one hardware entity is randomly selected as an encryption hardware entity. The encryption hardware entity is determined based on the data encryption type. When the data is encrypted based on the source receiver and the encoder as the encryption hardware entity, the source signal received by the source receiver is determined. In the source encoding process, the source signal is encoded and encrypted by adjusting at least one of the data level, the transition of the signal edge, the rising edge and the falling edge, the physical information represented by the bit, and the bit compression information. For example, the specific content of the physical information represented by each bit, whether the bit information is compressed, that is, the first numerical bit is used to represent the second numerical bit information. The source encoding method is recorded and randomly added to the transmitted data.

[0056] According to the embodiments of the present disclosure, a clock signal is generated by using a clock circuit in a hardware entity that transmits data between a cloud terminal and a cloud server, data transmitted in hardware entities such as a source receiver, encoder, modulator and frequency converter controlled by the clock signal is encrypted, the source receiver and encoder are controlled to encrypt the data, the source signal is encoded and encrypted during the source encoding process, and the encrypted data is transmitted to the cloud server, thereby achieving hardware-level encryption when the cloud terminal transmits data to the cloud server, thereby ensuring safe data use.

[0057] Figure 6 is a flowchart of a data transmission method according to another exemplary embodiment of the present disclosure. Figure 6 As shown, the data transmission method includes the following steps.

[0058] In step S401, the data encryption type of data transmitted from the cloud terminal to the cloud server is determined.

[0059] In step S402, an encryption hardware entity is determined based on the data encryption type.

[0060] In step S403, if the encryption hardware entity includes a source receiver and an encoder, a source signal received by the source receiver is determined.

[0061] In step S404, during the source coding process, the source signal is encoded and encrypted by adjusting at least one of the data level, the transition of the signal edge, the rising edge and the falling edge, the physical information represented by the bit, and the bit compression information.

[0062] In step S405, in the process of encrypting the source signal, anti-interference capability coding is used for encoding.

[0063] In step S406, the encrypted data is transmitted to the cloud server.

[0064] In the disclosed embodiment, the cloud terminal transmits data to the cloud server, and the data is encrypted by the hardware entity. Among the multiple hardware entities that transmit data between the cloud terminal and the cloud server, at least one hardware entity is randomly selected as the encryption hardware entity. The encryption hardware entity is determined based on the data encryption type. When the data is encrypted based on the source receiver and the encoder as the encryption hardware entity, the source signal received by the source receiver is determined. In the source encoding process, the source signal is encoded and encrypted by adjusting at least one of the high and low data levels, the transition of the signal edge, the rising edge and the falling edge, the physical information represented by the bit, and the bit compression information. In order to achieve the channel anti-interference capability of the encoding, anti-interference capability coding can be added. For example, in the encoding composed of 0 and 1 signals, there are too many 0s. In order to use anti-interference capability coding for encoding, some 1s can be randomly added at random positions to balance the relative number of 0 and 1 signals in the circuit, thereby stabilizing the circuit. When encoding using anti-interference capability coding, the encoding position Xi and the number Num-j are added to form coordinates (Xi, Num-j), where i, j = 0, 1, 2, 3...n. The bit information generated by adding the anti-interference capability coding is exchanged between the i-th bit information and the j-th bit information, and the exchanged information is recorded and added to the transmission data. The transmission data is then verified, and the bit data information is recorded and added to the transmission data for data transmission.

[0065] According to the embodiments of the present disclosure, a clock signal is generated by using a clock circuit in a hardware entity that transmits data between a cloud terminal and a cloud server, data transmitted in hardware entities such as a source receiver, encoder, modulator and frequency converter controlled by the clock signal is encrypted, the source receiver and encoder are controlled to encrypt the data, the source signal is encoded and encrypted during the source encoding process, encoded using anti-interference capability encoding, and the encrypted data is transmitted to the cloud server, thereby achieving hardware-level encryption when the cloud terminal transmits data to the cloud server, thereby ensuring safe data use.

[0066] Figure 7 is a flowchart of a data transmission method according to another exemplary embodiment of the present disclosure. Figure 7 As shown, the data transmission method includes the following steps.

[0067] In step S501, the data encryption type of data transmitted from the cloud terminal to the cloud server is determined, where the data encryption type is used to indicate an encryption hardware entity that encrypts the data.

[0068] In step S502, the encryption hardware entity is determined based on the data encryption type. If the encryption hardware entity includes a modulator, the modulation method used by the modulator in the digital modulation process is determined.

[0069] In step S503, the number information corresponding to the modulation method is added to the modulated data information, and the modulation method to be used is determined based on the number information during the analog modulation process, and the analog modulation is performed using the same modulation method as in the digital modulation process.

[0070] In step S504, the encrypted data is transmitted to the cloud server.

[0071] In the disclosed embodiment, the cloud terminal transmits data to the cloud server, encrypts the data with a hardware entity, and selects an encryption hardware entity from multiple hardware entities that transmit data between the cloud terminal and the cloud server. The encryption hardware entity is at least one hardware entity randomly selected from the hardware entities that transmit data between the cloud terminal and the cloud server, and the encryption hardware entity is determined based on the data encryption type. The data is encrypted based on the modulator as an encryption hardware entity, and the modulation method used by the modulator in the digital modulation process is determined. The number information corresponding to the modulation method is added to the modulated data information, and the modulation method can be controlled according to the micro control unit, for example, the modulation amplitude shift keying method ask, frequency shift keying method fsk, phase shift keying method psk, orthogonal phase shift keying qpsk or orthogonal amplitude modulation qam at the digital end. The digital segment modulation is encoded into the code DataMou-i, recorded and added to the transmission data. In the analog modulation process, the modulation method used is determined based on the number information, and the same modulation method as in the digital modulation process is used for analog modulation, and the same encoding AnalogMou-j is performed on the analog segment modulation method, which is recorded and added to the transmission data.

[0072] According to the embodiment of the present disclosure, by using a modulator in a hardware entity that transmits data between a cloud terminal and a cloud server to encrypt the transmitted data during the digital modulation process, and transmitting the encrypted data to the cloud server, hardware-level encryption is achieved when the cloud terminal transmits data to the cloud server, thereby ensuring the security of data use.

[0073] Figure 8 is a flowchart of a data transmission method according to another exemplary embodiment of the present disclosure. Figure 8 As shown, the data transmission method includes the following steps.

[0074] In step S601, based on the security level of the data to be transmitted, a data encryption type matching the security level is determined.

[0075] In step S602, the encryption hardware entity encrypts the data based on the data encryption type indication, and transmits the encrypted data to the cloud server.

[0076] In the disclosed embodiment, the cloud terminal transmits data to the cloud server, encrypts the data using a hardware entity, and selects an encryption hardware entity from among the multiple hardware entities that transmit data between the cloud terminal and the cloud server. The encryption hardware entity is at least one hardware entity randomly selected from the hardware entities that transmit data between the cloud terminal and the cloud server. Based on the security level of the data to be transmitted, the data encryption type that matches the security level is determined. For example, if the data to be transmitted is of low importance and will not cause harm to the user even if intercepted, the data encryption type that matches the security level is determined to be a lower level. If the data to be transmitted is of high importance, such as identity information, password information, account information, etc., the data encryption type that matches the security level is determined to be a higher level. For data to be transmitted that is of high importance, that is, the illegal acquisition of data may damage the normal operation of the cloud terminal and put the cloud terminal in danger. For example, if the data to be transmitted is charging information, voltage regulation information, etc., a higher level is adopted, or the highest level of data encryption type is determined according to usage requirements.

[0077] Different security levels correspond to different data encryption types, that is, different security levels correspond to different determined encryption hardware entities. For example, different data encryption types correspond to different encryption hardware entities. For data encryption types with higher importance, there are relatively more encryption hardware entities corresponding to them, and their encryption levels are increased. Data encryption types with lower importance correspond to relatively fewer encryption hardware entities. For another example, the encryption methods used by the same encryption hardware entity may be different. For data encryption types with higher importance and data encryption types with lower importance, when determining that the same encryption hardware performs data encryption, the data encryption types with higher importance use a higher level of encryption method, and the data encryption types with lower importance use a lower level of encryption method.

[0078] Based on the same concept, an embodiment of the present disclosure also provides a data transmission device.
