Description

Technical Field

[0001] This disclosure relates to the field of data processing technology, and in particular to a data transmission method, apparatus, device, and storage medium. Background Technology

[0002] At present, the information security development of vehicle electronic control units (ECUs) is gradually receiving attention. The security development of ECU information mostly relies on the porting of fixed cryptographic algorithms. Each cryptographic algorithm has a corresponding interface function, and the ECU will call different cryptographic algorithm functions through the interface function.

[0003] However, in real-world applications, the applications configured in an ECU typically need to call multiple cryptographic algorithms to process data. This means that multiple interface functions are required to call the corresponding cryptographic algorithms, which can easily lead to confusion in software design interface information and data. Furthermore, ECU information security development engineers need to maintain multiple interface functions and provide documentation for them, resulting in slower ECU development and iteration speeds, thus impacting the development schedule and extending the development cycle. Summary of the Invention

[0004] To solve the above-mentioned technical problems, or at least partially solve them, this disclosure provides a data transmission method, apparatus, device, and storage medium that can reduce chaos during data transmission, facilitate maintenance, and improve processing efficiency.

[0034] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0035] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0036] Specifically, the information security development of in-vehicle electronic control units (ECUs) is receiving increasing attention. The secure development of ECU information largely relies on porting fixed cryptographic algorithms, including Advanced Encryption Standard (AES), RSA, SHA1, and Elliptic Curve Cryptography (ECC). Each algorithm has a corresponding interface function, which the applications (APPs) deployed in the ECU need to call during use. However, in practice, ECUs often need to call multiple cryptographic algorithm functions depending on the application scenario. This means there may be situations where a large number of different interface functions need to be called, or different applications may need to call the same cryptographic algorithm corresponding to a single interface function simultaneously. This easily leads to confusion in software design interface information and data transmission, resulting in low processing efficiency. Furthermore, ECU information security development engineers also need to maintain multiple interface functions and provide documentation for them, slowing down the development speed of ECUs, impacting the development schedule, and increasing the development cycle.

[0037] For example, in related technologies, see Figure 1 The application 110 deployed in the vehicle's electronic control unit needs to call the corresponding cryptographic algorithm for processing. The cryptographic algorithm refers to the processing method corresponding to the aforementioned algorithm identifier. It needs to send request information to the corresponding cryptographic algorithm interface function and receive return information. For example, Figure 1The interface includes four cryptographic algorithms: Encryption 130, Decryption 140, Signature 150, and Hash 160. When application 110 needs to encrypt data, it sends a request to Encryption 130. When another part of application 110's data needs to be signed, it sends a request to Signature 150. Simultaneously, application 120 also needs to encrypt some data, so it sends a request to Encryption 130. Encryption 130 receives the requests from both applications 110 and 120, processes them using the encryption algorithm, and then sends a return message back to both applications. During data transmission, Encryption 130 may receive multiple requests and send multiple returns, which can easily lead to confusion in the software interface and data transmission, preventing fast, orderly, and accurate data transmission. The data transmission from applications 110 and 120 to Decryption 140 and Hash 160 is similar to the data transmission to Encryption 130 and Signature 150. In addition, the information security development engineer of the electronic control unit needs to maintain 4 interface functions and provide the corresponding documentation for the 4 interface functions, which will also affect the development progress of the vehicle electronic control unit.

[0038] Specifically, to address the aforementioned technical problems, this disclosure provides a data transmission method. By acquiring request information, which includes target data and identification information, and automatically determining the algorithm identifier based on the identification information using a pre-established interface function, the method automatically determines the algorithm identifier corresponding to the target method among multiple processing methods. In other words, the pre-established interface function automatically determines the algorithm identifier corresponding to the target method represented in the identification information. The target method is then called to process the target data included in the request information, obtaining a processing result. This processing result can be data obtained after encrypting, decrypting, or signing the target data. By constructing a single interface function, the algorithm identifier corresponding to the target method among multiple processing methods can be automatically identified, enabling fast, orderly, and accurate data transmission, avoiding data corruption during data transmission, achieving high processing efficiency, and facilitating the maintenance of the interface function.

[0039] Specifically, the data transmission method provided in this disclosure will be further described in detail through one or more of the following embodiments.

[0040] Figure 2 A flowchart illustrating a data transmission method provided in an embodiment of this disclosure. This includes, for example: Figure 2 The following steps S210 to S230 are shown:

[0041] S210. Obtain request information, which includes target data and identification information.

[0042] Understandably, the vehicle electronic control unit obtains request information from the application, which includes target data and identification information. Target data refers to the data processed by calling cryptographic algorithms, and identification information includes information about the specific cryptographic algorithm (target method) that the application needs to call.

[0043] S220. Based on the identification information, determine the algorithm identifier using a pre-established interface function. The interface function is used to determine the algorithm identifier corresponding to the target method among multiple processing methods.

[0044] Understandably, based on the above S210, a pre-established interface function is used to identify the algorithm identifier corresponding to the target method in the identification information. The algorithm identifier refers to the identifier corresponding to one of multiple pre-constructed cryptographic algorithms. One identification information includes information about a target method, and one target method corresponds to one algorithm identifier. The target data is processed through the target method corresponding to each algorithm identifier. Specifically, the pre-established interface function can identify the algorithm identifier corresponding to the target method among multiple processing methods. That is, for any application's request information, for example, if the application needs to call an encryption algorithm to encrypt data, the pre-established interface function can automatically identify the encryption algorithm to be called by the application, and then call that encryption algorithm to encrypt the data that needs to be encrypted in the application. Understandably, in related technologies, one cryptographic algorithm corresponds to one interface function; in this disclosure, one interface function corresponds to multiple cryptographic algorithms. This interface function can automatically identify the algorithm identifier corresponding to a specific cryptographic algorithm in the identification information, and then call the specific cryptographic algorithm for processing according to the algorithm identifier. This can effectively avoid data transmission chaos and ensure orderly data transmission.

[0045] For example, see Figure 3 , Figure 3 This is a schematic diagram of data transmission provided in an embodiment of the present disclosure. Application 310 sends request information to a pre-established interface function 330. The interface function 330 includes algorithm identifiers corresponding to various processing methods such as encryption, decryption, signature verification, and hashing. The interface function 330 identifies the algorithm identifier corresponding to the identifier information. For example, the interface function 330 identifies the algorithm identifier corresponding to the identifier information sent by application 310 as an encryption identifier, and the interface function 330 identifies the algorithm identifier corresponding to the identifier information sent by application 320 as a hash identifier.

[0046] Understandably, the request information sent by applications 310 and 320 can be stored in the cache queue of the vehicle electronic control unit. Following a first-in, first-out (FIFO) principle, the interface function is called to identify the identifier information of the request information in the cache queue. For example, after processing the request information from application 310, interface function 330 processes the request information sent by application 320.

[0047] S230. Call the target method corresponding to the algorithm identifier to process the target data and obtain the processing result.

[0048] Understandably, based on the above S220, the vehicle electronic control unit calls the target method corresponding to the algorithm identifier to process the target data in the request information. The processing methods include encryption / decryption algorithms, signature verification algorithms, or hash algorithms, etc. The target method is one of the processing methods. The processing result is obtained and returned to the application that sent the request information.

[0049] For example, see Figure 3 After the application 310 sends the request information, the interface function 330 identifies the identification information in the request information and determines the algorithm identifier. Then, it calls the target method corresponding to the algorithm identifier to process the target data in the request information, obtains the processing result, and returns the processing result to the application 310, thus completing the fast and orderly transmission of data.

[0050] Optionally, the interface function can be a program written in a programming language, such as C. The interface function can be configured between the application layer and the underlying layer of the vehicle electronic control unit (VECU). The underlying layer can port cryptographic algorithms from various related technologies according to user needs; for example, it can port algorithms such as AES, RSA, SHA, and ECC. The application layer consists of multiple applications installed in the VECU. The application layer of the VECU sends request information and receives return information. The interface function receives the request information, calls the underlying cryptographic algorithm to process the target data in the request information, and returns the processing result (return information) to the application layer.

[0051] Optionally, the interface function may include: an interface function declaration and an enumeration variable definition. The interface function declaration includes information such as the names of the variables included in the interface function, which describes which variables are included in the program of the interface function. The enumeration variable definition includes the process of determining the specific variable value corresponding to each variable, and can pass parameters, judge and identify the variables input to the interface function according to the interface function declaration.

[0052] Understandably, the documentation for interface functions can be as shown in Table 1. The documentation for interface functions refers to the explanation and comments on each variable and its value in the program of the interface function.

[0053] Table 1

[0054]

[0055] Understandably, in column 1, the suffix "variable" indicates the definition of the variable type, and column 2 indicates the name and meaning of each variable included in the interface function in the program of the interface function, that is, it shows the symbol and meaning of each variable value.

[0056] For example, referring to Table 1, the formal parameter enumeration variables in column 1 include usage and direction. The enumeration values ​​in column 1 include Cipher (encryption / decryption), Signature (signature verification), and Hash (hash). That is, the variable value list for usage is {Cipher, Signature, Hash}, and the variable value for usage can be selected from the variable value list. For example, if the application needs to encrypt or decrypt the target data, the variable value for usage is Cipher (encryption / decryption); if the application needs to sign and verify the target data, the variable value for usage is Signature (signature verification). The suffix of any row in Table 1 is the parameter of the variable, and the enumeration value of the next row is the variable value corresponding to the variable in the previous row. Similarly, the descriptions of the variable values ​​corresponding to other variables can be obtained, which will not be elaborated here.

[0057] This disclosure discloses a data transmission method that obtains request information, including target data and identification information. The identification information includes information about the target method. Then, a pre-established interface function is used to automatically determine the algorithm identifier corresponding to the identification information. The target method corresponding to the algorithm identifier is then called to process the target data in the request information, resulting in a processing result. This data transmission method, through a pre-built interface function, can automatically identify the cryptographic algorithm identifier corresponding to the target method among multiple processing methods. It processes the target data according to the identified target method corresponding to the specific cryptographic algorithm identifier, effectively reducing data transmission chaos, ensuring orderly data transmission, and offering simple operation, high flexibility, and high processing efficiency. Furthermore, the development engineer of the electronic control unit only needs to maintain one interface function and provides a description of the interface function, further accelerating the research and development process.

[0058] Based on the above embodiments, optionally, the algorithm identifier can be determined using a pre-established interface function based on the identifier information, specifically including the following:

[0059] Optionally, the identification information includes multiple variable identifiers corresponding to the target method among multiple processing methods.

[0060] Understandably, the identification information in the request information generated by the application includes multiple variable identifiers corresponding to the target method among multiple processing methods. The first variable identifier among these multiple variable identifiers is used to initially determine the scope of the target data that the application needs to process. For example, the first variable identifier can refer to the variable usage in Table 1, which determines whether encryption / decryption, signature verification, or hashing operations are performed. The second variable identifier among these multiple variable identifiers can refer to any one of the variables mode, standard usage, and hash algorithm in Table 1. The third variable identifier among these multiple variable identifiers can refer to the variable direction in Table 1. Understandably, the number of variable identifiers included in the identification information can be determined according to the actual application requirements.

[0061] Optionally, the algorithm identifier is determined using a pre-established interface function based on the identifier information. Specifically, if the first variable identifier among the multiple variable identifiers in the identifier information is a first preset identifier, the second variable identifier among the multiple variable identifiers is a second preset identifier, and the third variable identifier among the multiple variable identifiers is a third preset identifier, then the algorithm identifier is determined based on the first preset identifier, the second preset identifier, and the third preset identifier.

[0062] Understandably, the identification information is identified using a pre-established interface function. If the first variable identifier among the multiple variable identifiers in the identification information is a first preset identifier, the second variable identifier among the multiple variable identifiers is a second preset identifier, and the third variable identifier among the multiple variable identifiers is a third preset identifier, then the algorithm identifier corresponding to the identification information is determined based on the first preset identifier, the second preset identifier, and the third preset identifier. Here, the first preset identifier, the second preset identifier, and the third preset identifier are the variable values ​​corresponding to each variable in Table 1 above. The first preset identifier can be the identifier of one of the variable values ​​Cipher (encryption / decryption), Signature (signature verification), and Hash (hash) in Table 1.

[0063] Optionally, when the first preset identifier is an encryption / decryption identifier, the second preset identifier is a first encryption / decryption algorithm identifier, and the third preset identifier is an encryption identifier or a decryption identifier.

[0064] Understandably, when the first preset identifier is an encryption / decryption identifier, that is, when the first preset identifier is the variable value Cipher, the system continues to determine whether the second preset identifier is the first encryption / decryption algorithm identifier. The second preset identifier can be one of the variable values ​​corresponding to the variable mode in Table 1 above, which corresponds to the first preset identifier. The second preset identifier can be one of the variable values ​​of ECB (AES encryption / decryption mode), CB (AES encryption / decryption mode), CFB (AES encryption / decryption mode), and OFB (AES encryption / decryption mode). The third preset identifier is an encryption identifier or a decryption identifier. The third preset identifier can be one of the variable values ​​of direction in Table 1 corresponding to the first preset identifier. The third preset identifier can be DIR_ENCRYPT (encryption) or DIR_DECRYPT (decryption).

[0065] Optionally, when the first preset identifier is the signature verification identifier, the second preset identifier is the first signature verification algorithm identifier, and the third preset identifier is the generation identifier or the verification identifier.

[0066] Understandably, when the first preset identifier is a signature verification identifier, that is, when the first preset identifier is the variable value Signature, the system continues to determine whether the second preset identifier is the first signature verification algorithm identifier corresponding to the first preset identifier. The second preset identifier can be the identifier of one of the variable values ​​corresponding to the variable standard in Table 1 above, which corresponds to the first preset identifier. The second preset identifier can be the identifier of RSAPSS (RSA signature verification standard) or RSASSA_Pkcs1_v15 (RSA signature verification standard). The third preset identifier is a generation identifier or a verification identifier. The third preset identifier can be the identifier of one of the variable values ​​corresponding to the direction in Table 1, which corresponds to the first preset identifier. The third preset identifier can be DIR_GENERATE (generation) or DIR_VERIFY (verification).

[0067] Optionally, when the first preset identifier is a hash identifier, the second preset identifier is a hash algorithm identifier, and the third preset identifier is a generation identifier or a verification identifier.

[0068] Understandably, when the first preset identifier is a hash identifier, that is, when the first preset identifier is the variable value Hash, the system continues to determine whether the second preset identifier is the hash algorithm identifier corresponding to the first preset identifier. The second preset identifier can be the identifier of one of the variable values ​​corresponding to the variable hashalgo (hash algorithm) corresponding to the first preset identifier in Table 1 above. The second preset identifier can be MD5 (message digest algorithm) or SHA series algorithm (secure hash algorithm). The third preset identifier is a generation identifier or a verification identifier. The third preset identifier can be the identifier of one of the variable values ​​of the direction (direction) corresponding to the first preset identifier in Table 1. The third preset identifier can be DIR_GENERATE (generation) or DIR_VERIFY (verification). The identifier of the variable value of the third preset identifier corresponding to the hash identifier is the same as the identifier of the variable value of the third preset identifier corresponding to the signature verification identifier.

[0069] This disclosure provides a data transmission method that identifies the algorithm identifier corresponding to the identification information through a pre-established interface function. If the first variable identifier among the multiple variable identifiers in the identification information is a first preset identifier, the second variable identifier among the multiple variable identifiers is a second preset identifier, and the third variable identifier among the multiple variable identifiers is a third preset identifier, then the algorithm identifier is determined based on the first preset identifier, the second preset identifier, and the third preset identifier. This method can automatically identify the algorithm identifier corresponding to the multiple variable identifiers included in the identification information using a single interface function. The identification speed is relatively fast, the identification accuracy is relatively high, and the orderly transmission of data is also guaranteed.

[0070] Based on the above embodiments, Figure 4 This is a flowchart illustrating a data transmission method provided in an embodiment of this disclosure. If the interface function cannot identify the algorithm identifier corresponding to the identifier information, then the following steps are performed: Figure 4 The following steps S410 to S430 are shown:

[0071] Understandably, when using the interface function to automatically identify the algorithm identifier corresponding to the identifier information, there may be situations where the identification range of the interface function is exceeded, or other situations where it cannot be identified. In this case, fault information can be generated for each step that cannot be identified, and subsequent maintenance personnel can analyze and maintain the interface function based on the fault information.

[0072] S410. If the first variable identifier is not the first preset identifier, then generate the first fault information.

[0073] Understandably, if the first variable identifier is not the first preset identifier, that is, if the first variable identifier is not the identifier of one of the variable values ​​Cipher (encryption / decryption), Signature (signature verification), and Hash (hash) in Table 1, it is outside the recognition range of the interface function. In this case, the first fault information can be generated. The first fault information may include the first variable identifier and information about the specific steps that cannot be recognized.

[0074] S420. If the first variable identifier is the first preset identifier and the second variable identifier is not the second preset identifier, then generate the second fault information.

[0075] Understandably, if the first variable identifier is the first preset identifier, but the second variable identifier is not the second preset identifier (i.e., the second variable identifier is neither the first nor the second encryption / decryption algorithm identifier), a second fault message can be generated. This second fault message can include the second variable identifier and information about the specific steps that cannot be identified. Maintenance personnel will then add the corresponding algorithm identifier to the interface function's preset identifier library based on the generated second fault message, further expanding the storage capacity of the preset identifier library within the interface function.

[0076] S430. If the first variable identifier is a preset algorithm identifier, the second variable identifier is a second preset identifier, and the third variable identifier is not a third preset identifier, then generate third fault information.

[0077] Understandably, if the first variable identifier is the first preset identifier, the second variable identifier is the second preset identifier, and the third variable identifier is not any of the third preset identifiers, then a third fault message is generated and returned to the application. This allows maintenance personnel to analyze and maintain the interface function based on the third fault message. The second preset identifier can be either the first encryption / decryption algorithm identifier or the second encryption / decryption algorithm identifier. The third preset identifier includes an encryption identifier, a decryption identifier, a generation identifier, and a verification identifier.

[0078] The data transmission method provided in this disclosure provides a mechanism for generating fault information by setting up a mechanism for generating fault information in each operation step of the interface function. This facilitates maintenance personnel to analyze the different fault information generated and maintain or update the interface function in a timely manner, thus providing high flexibility.

[0079] Based on the above embodiments, Figure 5This is a flowchart illustrating a data transmission method provided in an embodiment of this disclosure. It is understood that the following steps are a detailed description of the encryption and decryption operations performed on target data in request information by an interface function; that is, the interface function identifies the corresponding algorithm identifier based on the identifier information included in the request information, and processes the data according to the processing method corresponding to the algorithm identifier. Optionally, the process of determining the algorithm identifier based on a first preset identifier, a second preset identifier, and a third preset identifier, i.e., determining the encryption / decryption algorithm and performing the processing, specifically includes, as follows: Figure 5 The following steps S510 to S520 are shown:

[0080] S510. If the first preset identifier is an encryption / decryption identifier, the second preset identifier is a first encryption / decryption algorithm identifier, and the third preset identifier is an encryption identifier, then the algorithm identifier is determined to be the identifier corresponding to the first encryption algorithm.

[0081] Understandably, if the first preset identifier is an encryption / decryption identifier, then it can be further determined whether the second preset identifier is the first encryption / decryption algorithm identifier. If so, it can be further determined whether the third preset identifier is an encryption identifier. If so, the algorithm identifier can be directly determined to be the identifier corresponding to the first encryption algorithm. The first encryption / decryption algorithm identifier can be an identifier of an Advanced Encryption / Decryption Algorithm (AEC encryption / decryption mode). Specifically, the identifiers for AES encryption / decryption mode include those for Electronic Codebook (ECB), Cipher-Block Chaining (CBC), Cipher Feedback (CFB), and Output Feedback (OFB). In other words, the first preset identifier can be any of the identifiers for the first encryption / decryption algorithm. The encryption identifier can correspond to the identifier of the variable value DIR_ENCRYPT (encryption) in Table 1 above. For example, if the first encryption / decryption algorithm identifier is the identifier of the ECB algorithm, then the first encryption algorithm can be the ECB encryption algorithm.

[0082] S520: Call the first encryption algorithm to process the target data and obtain the first encrypted data.

[0083] Understandably, based on the above S510, after determining the algorithm identifier, the target data is encrypted using the first encryption algorithm. The first encryption algorithm can be the first encryption algorithm corresponding to the above AES encryption and decryption mode. The AES encryption function (first encryption algorithm) is called and the mode, symmetric algorithm key, offset vector and plaintext are transmitted. The first encrypted data obtained can be the ciphertext after encrypting the target data.

[0084] Optionally, if the first preset identifier is an encryption / decryption identifier, the second preset identifier is a first encryption / decryption algorithm identifier, and the third preset identifier is a decryption identifier, then the algorithm identifier is determined to be the identifier corresponding to the first decryption algorithm; the first decryption algorithm is called to process the target data to obtain the first decrypted data.

[0085] Understandably, if the first preset identifier is an encryption / decryption identifier, then it continues to determine whether the second preset identifier is the first encryption / decryption algorithm identifier corresponding to the encryption / decryption identifier. If so, it continues to determine whether the third preset identifier is a decryption identifier. The decryption identifier can correspond to the identifier of the variable value DIR_DECRYPT (decryption) in Table 1 above. If the third preset identifier is a decryption identifier, then the first decryption algorithm corresponding to the first encryption / decryption algorithm identifier is used to decrypt the target data. The first decryption algorithm can be the first decryption algorithm corresponding to the AES encryption / decryption mode mentioned above. After determining the first decryption algorithm, the AES decryption function (first decryption algorithm) is called and the mode, symmetric algorithm key, offset vector and ciphertext are passed. Finally, the first decrypted data can be the plaintext after decrypting the target data.

[0086] Optionally, when the first preset identifier is an encryption / decryption identifier, the second preset identifier is a second encryption / decryption algorithm identifier, and the third preset identifier is an encryption identifier or a decryption identifier.

[0087] Understandably, when the first preset identifier is the encryption / decryption identifier, the second preset identifier is the second encryption / decryption algorithm identifier. That is, the encryption / decryption identifier includes identifiers for multiple encryption / decryption algorithms. The second preset identifier may be either the first or second encryption / decryption algorithm identifier to ensure that the pre-established interface functions can recognize identifiers for multiple encryption / decryption algorithms. For example, the second encryption / decryption algorithm identifier could be an identifier for a standard encryption algorithm (RSA encryption / decryption standard). Specifically, the identifier for a standard encryption algorithm (RSA encryption / decryption standard) could include identifiers for OAEP (RSA encryption / decryption standard) and Pkcs1v15 (RSA encryption / decryption standard).

[0088] Optionally, after adding a second encryption / decryption algorithm identifier, the algorithm identifier is determined based on the first preset identifier, the second preset identifier, and the third preset identifier. Specifically, if the first preset identifier is an encryption / decryption identifier, the second preset identifier is a second encryption / decryption algorithm identifier, and the third preset identifier is an encryption identifier, then the algorithm identifier is determined to be the identifier corresponding to the second encryption algorithm; if the first preset identifier is an encryption / decryption identifier, the second preset identifier is a second encryption / decryption algorithm identifier, and the third preset identifier is a decryption identifier, then the algorithm identifier is determined to be the identifier corresponding to the second decryption algorithm.

[0089] Understandably, after adding the second encryption / decryption algorithm identifier, the subsequent method for determining the algorithm identifier is the same as the process for determining the first encryption / decryption algorithm identifier, and will not be elaborated here. Specifically, the identifier of the second encryption / decryption algorithm can be the identifier corresponding to any one of the following algorithms: RSA, SHA1, and ECC.

[0090] Optionally, after determining the algorithm identifier corresponding to the second encryption / decryption algorithm identifier, the second encryption algorithm is called to process the target data to obtain the second encrypted data; the second decryption algorithm is called to process the target data to obtain the first decrypted data.

[0091] Understandably, the target data is encrypted using the second encryption algorithm corresponding to the second encryption algorithm identifier. The second encryption algorithm can be the encryption algorithm corresponding to the RES encryption and decryption standard mentioned above. After determining the second encryption algorithm, the RES encryption function (second encryption algorithm) is called and the standard, the asymmetric algorithm public key and the plaintext are passed. The final second encrypted data can be the ciphertext after encrypting the target data.

[0092] Understandably, the target data is decrypted using the second encryption / decryption algorithm identifier corresponding to the second decryption algorithm. The second decryption algorithm can be the decryption algorithm corresponding to the RES encryption / decryption standard mentioned above. After determining the second decryption algorithm, the RES decryption function (second decryption algorithm) is called and the standard, asymmetric algorithm private key and ciphertext are passed. The final decrypted data can be the plaintext after decrypting the target data.

Specifically, these steps include... Figure 7 The following steps S710 to S720 are shown:

[0127] Understandably, the signature verification identifier is used to determine whether the application needs to generate or verify a signature on the target data. If the first preset identifier is the signature verification identifier, the interface function calls the processing method corresponding to the signature verification identifier to process the target data in the request information and obtain the processing result. The processing method can be an algorithm that can generate a signature on the target data or an algorithm that can verify the signature on the target data. If a signature on the target data is generated, the processing result includes the signed message and the ciphertext. If the target data is verified by signature, the processing result includes the signed message and the signature value.

The first signature verification algorithm identifier can be the identifier of the RSA Private Key Signature Filling Standard (RSA-PSS) or the RSASA_Pkcs1_v15 Filling Standard in the RSA signature verification standard. That is, the second preset identifier can be any identifier in the first signature verification algorithm identifier. If the second preset identifier is the first signature verification algorithm identifier, then it is further determined whether the third variable identifier is a generation identifier. The generation identifier can correspond to the identifier of the variable value DIR_GENERATE (generation) in Table 1 above. If the third variable identifier is a generation identifier, then the first generation algorithm corresponding to the first signature verification algorithm identifier is used to perform signature generation processing on the target data. The first generation algorithm can be the generation algorithm corresponding to the above RSA signature verification standard.

That is, the second preset identifier can be any identifier in the first signature verification algorithm identifier. If the second variable identifier is the first signature verification algorithm identifier, then it is further determined whether the third variable identifier is a verification identifier. The verification identifier can be the identifier corresponding to the variable value DIR_VERIFY (verification) in Table 1 above. If the third variable identifier is a verification identifier, then the first verification algorithm corresponding to the first signature verification algorithm identifier is used to perform signature verification processing on the target data. The first verification algorithm can be the verification algorithm corresponding to the above RSA signature verification standard. After determining the first verification algorithm, the RSA signature function (first verification algorithm) is called and the standard, asymmetric algorithm private key and message are passed. Finally, the first verification data is obtained. The first verification data can include the message after the target data has been signed and verified.

[0134] Optionally, when the first preset identifier is the signature verification identifier, the second preset identifier is the second signature verification algorithm identifier, and the third preset identifier is the generation identifier or the verification identifier.

[0135] Understandably, when the first preset identifier is a signature verification identifier, the second preset identifier can also be a second signature verification algorithm identifier. That is, the signature verification identifier includes identifiers for multiple signature verification algorithms. The second preset identifier may be either the first signature verification algorithm identifier or the second signature verification algorithm identifier, to ensure that the pre-established interface functions can recognize identifiers for multiple signature verification algorithms. For example, the second signature verification algorithm identifier could be an identifier for the Elliptic Curve Signature Verification Standard (EDDSA).

[0136] Optionally, after adding a second signature verification algorithm identifier, the algorithm identifier is determined based on the first preset identifier, the second preset identifier, and the third preset identifier. Specifically, if the first preset identifier is a signature verification identifier, the second preset identifier is a second signature verification algorithm identifier, and the third preset identifier is a generation identifier, then the algorithm identifier is determined to be the identifier corresponding to the second generation algorithm; if the first preset identifier is a signature verification identifier, the second preset identifier is a second signature verification algorithm identifier, and the third preset identifier is a verification identifier, then the algorithm identifier is determined to be the identifier corresponding to the second verification algorithm.

[0137] Understandably, the method for determining the algorithm identifier after adding the second signature verification algorithm identifier is the same as the process for determining the first signature verification algorithm identifier, and will not be elaborated here.

[0138] Optionally, after determining the algorithm identifier corresponding to the second signature verification algorithm identifier, the second generation algorithm is called to process the target data to obtain the second generated data; the second signature verification algorithm is called to process the target data to obtain the second verification data.

[0139] Understandably, the second generation algorithm corresponding to the second verification algorithm is used to generate a signature on the target data. The second generation algorithm can be the generation algorithm corresponding to the EDSA signature verification standard mentioned above. After determining the second generation algorithm, the EDSA signature function (second generation algorithm) is called and the asymmetric algorithm private key and message are passed. The final second generated data can include the message after the target data is signed.

[0140] Understandably, the target data is signed and verified using the second verification algorithm corresponding to the second verification algorithm identifier. The second verification algorithm can be the verification algorithm corresponding to the EDSA signature verification standard mentioned above. The EDSA verification function is called and the asymmetric algorithm public key, message and signature value are passed. Finally, the second verification data is obtained. The second verification data can be the message and signature value after the target data has been signed and verified.

[0141] Optionally, when the first preset identifier is a signature verification identifier, the second preset identifier is a third signature verification algorithm identifier, and the third preset identifier is a generation identifier or a verification identifier; if the first preset identifier is a signature verification identifier, the second preset identifier is a third signature verification sub-identifier, and the third preset identifier is a generation identifier, then the third generation algorithm corresponding to the third signature verification algorithm identifier is called to process the target data to obtain the third generated data; or, if the first preset identifier is a signature verification identifier, the second preset identifier is a third signature verification algorithm identifier, and the third preset identifier is a verification identifier, then the third verification algorithm corresponding to the third signature verification algorithm identifier is called to process the target data to obtain the third verified data.

[0142] Understandably, the process for determining the algorithm identifier corresponding to the third verification algorithm identifier is the same as the process for determining the first and second verification algorithm identifiers, and will not be repeated here. The third verification algorithm identifier can be the identifier corresponding to the Edwards Curve Signature Verification Standard (ECDSA Signature Verification Standard).

[0143] The data transmission method provided in this embodiment automatically identifies the first variable identifier as the signature verification identifier in the first preset identifier, and further calls the processing method corresponding to the signature verification identifier to process the target data and obtain the processing result. It can automatically identify the algorithm identifier corresponding to the identifier information, and call the corresponding processing method to perform signature generation or signature verification processing on the target data according to the identification result. It has fast processing efficiency, high identification accuracy, and strong flexibility.
