[0065] In order to make the technical problems to be solved by the present application, technical solutions and beneficial effects clearer, the present application will be further described in detail below with reference to the drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present application and not intended to limit the present application.

[0066] In addition, the terms "first", "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0067] In some application scenarios, an electronic device needs to transmit to-be-processed data to other electronic devices or servers, and perform corresponding special functions based on the to-be-processed data through the other electronic devices or servers. In the embodiments of the present application, the electronic device that sends the to-be-processed data is defined as a first electronic device, and the electronic device that receives the to-be-processed data is defined as a second electronic device. Correspondingly, the first electronic device can be a client, a host device, etc.; and the second electronic device can be a server, a slave device, etc.

[0068] When the first electronic device and the second electronic device perform data transmission, there may be a problem that the data is intercepted in the process of data transmission. If encryption means is not used, the data is easily read and tampered after being intercepted, especially in a public network environment, the data security risk is extremely high.

[0069] In some embodiments, in order to improve the security of data transmission, a large-computational-complexity encryption algorithm is used for encryption, for example, an asymmetric encryption algorithm (Rivest-Shamir-Adleman, RSA). However, since such an algorithm has large computational complexity, it has high requirements on the hardware performance of a device, occupies too much processing time of a processor, causes high energy consumption, and is not suitable for low-power-consumption devices with limited resources.

[0070] To sum up, in order to improve the security of data transmission and reduce the complexity of encryption calculation, so that the energy consumption of the encryption process is small and the encryption process is suitable for low-power-consumption devices, the present application provides a data transmission method, an electronic device, and a storage medium. By storing the serial number of the first electronic device, when it is necessary to send the to-be-processed data to the second electronic device, the plurality of bytes in each frame of data of the to-be-processed data are subjected to an exclusive-OR operation according to the stored serial number of the first electronic device, to obtain encrypted to-be-processed data, and then the encrypted to-be-processed data is sent to the second electronic device. In this way, the data to be transmitted is encrypted, the encryption key of each first electronic device is ensured to be unique, the security of data transmission is ensured, and the complexity of encryption calculation is reduced by performing the exclusive-OR operation on the bytes in the to-be-processed data by using the serial number of the first electronic device, thereby reducing the energy consumption generated in the encryption process, and the method is more suitable for low-power-consumption devices. Moreover, the to-be-processed data is encrypted by using the serial number of the first electronic device, since the serial numbers of different electronic devices are different, that is, the serial numbers are unique, the encryption method for the data is also unique, and the security of encryption is further ensured.

[0071] The present application will be described below in conjunction with specific embodiments. First, the application scenario of the present application is described. Referring to Figure 1 which shows a schematic diagram of a data transmission system designed by the data transmission method provided in an example embodiment. Parameters Figure 1 The data transmission system includes a first electronic device 10 and a second electronic device 20. A communication connection is established between the first electronic device 10 and the second electronic device 20. It should be noted that the communication connection between the first electronic device 10 and the second electronic device 20 can be in the form of a serial port wire or a wireless network, and in the embodiments of the present application, the communication connection mode between the first electronic device 10 and the second electronic device 20 is not limited.

[0072] Before data transmission, the first electronic device 10 establishes an association relationship with the second electronic device 20, so that the first electronic device 10 and the second electronic device 20 can perform encrypted data transmission. In the embodiments of the present application, the process of establishing an association relationship between the first electronic device 10 and the second electronic device 20 is not specifically limited. For example, the first electronic device 10 can install a target application, and the second electronic device 20 can be a server device of the target application. Accordingly, the first electronic device 10 can establish an association relationship with the second electronic device 20 by logging in an account of the target application.

[0073] The second electronic device 20 can establish an association relationship with at least one first electronic device 10. Therefore, after the first electronic device 10 establishes an association relationship with the second electronic device 20, the first electronic device 10 sends device information of the first electronic device 10 to the second electronic device 20, where the device information includes a serial number and a device identifier of the first electronic device 10. Accordingly, the second electronic device 20 receives the device information sent by the first electronic device 10, and stores the serial number and the device identifier in the device information, so that in subsequent decryption of encrypted to-be-processed data sent by the first electronic device 10, the serial number of the first electronic device 10 is determined according to the device identifier carried by the data, and the encrypted to-be-processed data is decrypted according to the serial number.

[0074] It should be noted that the device information can also include information such as the hardware version and the software version of the first electronic device 10. Since the hardware version information and the software version information of the first electronic device 10 and the like can be changed due to updates and the like during the running of the first electronic device 10, the first electronic device 10 needs to send updated device information to the second electronic device 20.

[0075] Accordingly, in some embodiments, when the first electronic device 10 detects software or hardware updates, the first electronic device 10 sends updated device information to the second electronic device 20. In other embodiments, the first electronic device 10 sends current device information to the second electronic device 20 every preset time interval. In other embodiments, the first electronic device 10 sends current device information to the second electronic device 20 every time it is powered on. In the embodiments of the present application, the timing of the first electronic device 10 sending device information to the second electronic device 20 is not specifically limited.

[0076] In the embodiments of the present application, the electronic device that sends to-be-processed data is defined as the first electronic device 10, and the electronic device that receives to-be-processed data is defined as the second electronic device 20. Accordingly, the first electronic device 10 can be a client, a host device, or the like; and the second electronic device 20 can be a server, a slave device, or the like. See Figure 2Fig. 1 shows a schematic diagram of the interaction between the first electronic device 10 and the second electronic device 20 according to an example embodiment. Referring to Fig. 1, Figure 2 The first electronic device 10 and the second electronic device 20 comprise a serial number storage module, a data encryption module, a data decryption module and a data processing module.

[0077] The first electronic device 10 stores the serial number assigned at the time of production in the serial number storage module, and reports the serial number and other device information to the second electronic device 20 when the first electronic device 10 is powered on. Correspondingly, the second electronic device 20 stores the device information reported by the first electronic device 10 in the serial number storage module when the device information is received. When the first electronic device 10 generates data to be processed, the first electronic device 10 encrypts the data to be processed through the data encryption module, and sends the data to be processed encrypted by the serial number to the second electronic device 20. The second electronic device 20 receives the encrypted data to be processed, decrypts the data to be processed through the data decryption module, and then analyzes and processes the decrypted data to be processed through the data processing module.

[0078] In some embodiments, the second electronic device 20 needs to send the processing result corresponding to the data to be processed to the first electronic device 10 as return data. Correspondingly, the second electronic device 20 encrypts the return data through the data encryption module, and then sends the encrypted data to the first electronic device 10. The first electronic device 10 decrypts the return data through the data decryption module, and then analyzes and processes the decrypted return data through the data processing module, thereby realizing the data interaction between the first electronic device 10 and the second electronic device 20.

[0079] It should be noted that the second electronic device 20 can use the serial number of the first electronic device 10 to decrypt the return data when encrypting the return data. In other embodiments, the second electronic device 20 can send the serial number of the second electronic device 20 to the first electronic device 10 in advance. Correspondingly, the second electronic device 20 can use the serial number of the second electronic device 20 to decrypt the return data, and the principle of this process is the same as that of using the serial number of the first electronic device 10 to encrypt, which will not be described here.

[0080] The data transmission method will be described below in conjunction with specific embodiments. Referring to Fig. 2, Figure 3 Fig. 2 shows a schematic diagram of a flowchart of a data transmission method according to an example embodiment. As an example and not limitation, the method is applied to a first electronic device.

[0081] S301, when it is necessary to send data to be processed to a second electronic device, the first electronic device obtains the serial number of the first electronic device, which is a unique identification code assigned to the first electronic device during production. The second electronic device is a device associated with the first electronic device and used for data processing.

[0082] The serial number is a unique identification code assigned by First Electronics and the device during production. The serial number is generally composed of multiple bytes. The length of the serial number can be any number of bytes. For example, the length of the serial number can be 17 bytes, 18 bytes, or 19 bytes. In the embodiments of the present application, the length of the serial number is not specifically limited.

[0083] The first electronic device is assigned a serial number during production, and the first electronic device can store this serial number in a serial number storage module. The serial number storage module can be a memory device within the first electronic device, such as a flash memory. In this step, when the first electronic device needs to send data to be processed to the second electronic device, the first electronic device obtains the serial number of the first electronic device from the serial number storage module.

[0084] One thing that needs to be explained is that in order to ensure that the second electronic device can correctly decrypt the encrypted data to be processed sent by the first electronic device, the first electronic device sends the device information of the first electronic device to the second electronic device when the first electronic device is turned on. The device information includes the serial number and device identification of the first electronic device.

[0085] The first electronic device may send the device information of the first electronic device to the second electronic device in a preset data format. The preset data format may be set as needed. In the embodiments of the present application, the preset data format is not specifically limited. For example, the preset data format may be JSON format or other custom format.

[0086] S302 : For each frame of data in the data to be processed, the first electronic device performs an XOR operation on multiple bytes in each frame of data to be processed according to the serial number to obtain encrypted data to be processed.

[0087] For each frame of data in the data to be processed, the first electronic device can perform an XOR operation on a plurality of bytes at a target position in each frame of data to be processed according to the serial number, thereby achieving encryption of the data to be processed. The plurality of bytes at the target position in each frame of data to be processed can be set as needed, and the target position in each frame of data to be processed can be the same or different. In the embodiments of the present application, the target position is not specifically limited. For example, the target position can be a specified position in the data to be processed set by a user. Alternatively, the target position can be the position of the last plurality of bytes of each frame of data to be processed.

[0088] Correspondingly, the step can be that the first electronic device starts from the last byte of each frame of data to be processed and the last byte of the serial number, performs an XOR operation on the i th byte of each frame of data to be processed and the i th byte of the serial number, and obtains an encryption field of each frame of data to be processed; replaces N bytes in each frame of data to be processed with the encryption field, and obtains encrypted data to be processed, the N bytes being the bytes subjected to the XOR operation.

[0089] In the implementation mode, each frame of data to be processed is encrypted in a right-justified mode. For example, the length of the serial number is 17 bytes, and correspondingly, the last 17 bytes of each frame of data to be processed are subjected to an XOR operation with the bytes at the corresponding positions in the serial number, and then the data of the plurality of bytes subjected to the XOR operation is replaced with the plurality of bytes in the original data to complete the encryption. It should be noted that when the length of the data to be processed is less than the length of the serial number, the bytes in the data to be processed are subjected to an XOR operation with the low-order bytes in the serial number in sequence.

[0090] In the implementation mode, a plurality of bytes in the data to be processed are subjected to an XOR operation with the serial number, and then the bytes subjected to the XOR operation are replaced with the plurality of bytes in the original data, thereby achieving encryption of the data to be processed. In this way, the data to be processed is subjected to an XOR operation with the serial number, which does not depend on a complex encryption protocol, is suitable for various devices and server architectures, is easy to integrate and promote, can be easily implemented on embedded devices or high-performance servers, has wide applicability, high compatibility and universality, and the XOR operation is a basic logical operator of a computer, has low computational complexity and low energy consumption, is suitable for low-power devices, can prolong battery life, and reduce operating costs.

[0091] S303, the first electronic device sends the encrypted data to be processed to the second electronic device.

[0092] The first electronic device can send the encrypted to-be-processed data to the second electronic device in a wired form through a serial port, or send the encrypted to-be-processed data to the second electronic device in a wireless form through a wireless network, which is not limited in the embodiment of the present application.

[0093] It should be noted that after the second electronic device receives the encrypted to-be-processed data sent by the first electronic device, the second electronic device decrypts the to-be-processed data based on the stored serial number of the first electronic device, analyzes and processes the decrypted to-be-processed data, obtains a processing result, and sends the processing result as feedback data to the first electronic device. In order to ensure the security of data transmission, the second electronic device also encrypts the feedback data. Correspondingly, the first electronic device decrypts the received feedback data to obtain the processing result corresponding to the to-be-processed data. The process includes: the first electronic device receives the feedback data sent by the second electronic device; the feedback data is decrypted according to the serial number, and the decrypted feedback data is analyzed and processed to obtain a processing result.

[0094] It should be noted that when the second electronic device encrypts the feedback data, the serial number of the first electronic device can be used to decrypt the feedback data. In another embodiment, the second electronic device can send the serial number of the second electronic device to the first electronic device in advance. Correspondingly, the second electronic device can use the serial number of the second electronic device to decrypt the feedback data. The principle of this process is the same as that of using the serial number of the first electronic device to encrypt, which will not be described here.

[0095] In the embodiment of the present application, by storing the serial number of the first electronic device, when it is necessary to send to-be-processed data to the second electronic device, the serial number of the first electronic device is used to perform an exclusive OR operation on a plurality of bytes in each frame of to-be-processed data to obtain encrypted to-be-processed data, and then the encrypted to-be-processed data is sent to the second electronic device. In this way, the data to be transmitted is encrypted, ensuring that the encryption key of each first electronic device is unique and ensuring the security of data transmission. Moreover, the exclusive OR operation on the bytes in the to-be-processed data by using the serial number of the first electronic device is simple in calculation, reduces the complexity of encryption calculation, thereby reducing the energy consumption generated in the encryption process, and is more suitable for low-power devices. Moreover, the serial number of the first electronic device is used to encrypt the to-be-processed data. Since the serial numbers of different electronic devices are different, that is, the serial numbers are unique, the encryption method of the data is also unique, further ensuring the security of encryption.

[0096] After the first electronic device sends the encrypted to-be-processed data to the second electronic device, the second electronic device decrypts the to-be-processed data based on the stored serial number of the first electronic device. Referring to Figure 4FIG. 1 shows a schematic diagram of a data transmission method flowchart provided by an exemplary embodiment. By way of example and not limitation, the method is applied to a second electronic device.

[0097] S401, when receiving the encrypted to-be-processed data sent by the first electronic device, the second electronic device acquires the serial number of the first electronic device, which is a unique identification code assigned to the first electronic device at production, and the first electronic device is an electronic device associated with the second electronic device and used to generate the to-be-processed data.

[0098] The to-be-processed data carries device information of the first electronic device, such as device identification, hardware version, software version, etc. of the first electronic device. Accordingly, after receiving the to-be-processed data, the second electronic device queries the corresponding serial number according to the device information such as the device identification carried by the to-be-processed data. The process can be: the second electronic device parses the encrypted to-be-processed data to obtain the device identification of the first electronic device sending the encrypted to-be-processed data; based on the device identification, the serial number corresponding to the device identification is queried.

[0099] The second electronic device stores the correspondence between the device identification and the serial number. Before this step, the second electronic device receives the device information sent by the first electronic device, which includes the device identification and the serial number of the first electronic device; and the device identification and the serial number of the first electronic device are stored correspondingly.

[0100] The second electronic device can be connected with multiple first electronic devices, and correspondingly, the second electronic device can store multiple sets of correspondence between the device identification and the serial number, and in the embodiments of the present application, the storage mode of the device identification and the serial number is not specifically limited. For example, the second electronic device correspondingly stores the device identification and the serial number in the form of a relationship table. The second electronic device can store the correspondence between the hardware version, the software version, etc. of the first electronic device and the serial number, which is not specifically limited in the embodiments of the present application.

[0101] S402, for each frame of data in the to-be-processed data, the second electronic device performs an exclusive or operation on multiple bytes in the encrypted to-be-processed data based on the serial number to obtain decrypted to-be-processed data.

[0102] The second electronic device performs an exclusive OR operation on a plurality of bytes in the encrypted to-be-processed data based on the serial number, replaces the plurality of bytes after the exclusive OR operation with corresponding bytes in the original data, and obtains decrypted to-be-processed data. The selection manner of the plurality of bytes is the same as the selection manner of the plurality of bytes in step S302, and will not be described again here. For example, still taking the 17-byte serial number as an example, the second electronic device extracts the last 17 bytes of each frame of data in the encrypted to-be-processed data, performs an exclusive OR operation on the last 17 bytes of the serial number of the first electronic device, and replaces the last 17 bytes of the original data with the data after the exclusive OR operation, thereby recovering the original data.

[0103] After the second electronic device decrypts the to-be-processed data, the second electronic device performs a corresponding target task function based on the to-be-processed data, obtains corresponding return data, encrypts the return data, and returns the encrypted return data to the first electronic device. This step can be: the second electronic device performs a target task function based on the decrypted to-be-processed data, obtains return data corresponding to the to-be-processed data, performs an exclusive OR operation on a plurality of bytes in the return data based on the serial number of the first electronic device, obtains encrypted return data, and sends the encrypted return data to the first electronic device.

In this way, the data to be transmitted is encrypted, the encryption key of each first electronic device is unique, the security of data transmission is ensured, and the exclusive OR operation on the bytes in the to-be-processed data based on the serial number of the first electronic device is simple to calculate, reduces the complexity of encryption calculation, thereby reducing the energy consumption generated in the encryption process, and is more suitable for low-power devices. In addition, the serial number of the first electronic device is used to encrypt the to-be-processed data. Since the serial numbers of different electronic devices are different, that is, the serial numbers are unique, the encryption manner of the data is also unique, and the security of the encryption is further ensured.
