Transmission Encryption Method, System, Device and Readable Storage Medium of Function Parameter Data
Technical Field The present invention relates to the field of data transmission technology, in particular to a transmission encryption method, system, device and readable storage medium of function parameter data.
Background Technology At present, when the function parameters are transmitted, it is generally necessary to encrypt the function parameters. In the prior art, all parameters are encrypted one by one when encrypting. Not only the process is cumbersome, but also the data is easily tampered with in the process of encrypting one by one. In addition, since the encryption process is relatively cumbersome, it will also affect the efficiency of data transmission. Furthermore, in the encryption process, most of the algorithms may adopt the same encryption method, and the encryption strength is not strong enough, which makes the encryption algorithm easy to be cracked and the data will be changed, etc., which causes the transmitted data to be altered or stolen.
Utility Model Contents Aiming at the shortcomings in the prior art, the present invention provides an encryption method, system, device and readable storage medium for function parameter data transmission. In order to solve the above technical problems, the present invention is solved by the following technical solutions: A method for encrypting function parameter data transmission includes the following steps: Get the function to be transmitted, and encrypt the parameters except the last bit in the function to obtain the desData value. The desData value is arranged based on the verification code, timestamp and digital signature. In the parameter data transmission process, the data sender transmits all the parameters of the function based on the last parameter of the function. During transmission, the last bit of parameters is spliced and combined to obtain the transmission string. The transmission string is formed by concatenating the symmetric encryption algorithm identifier, the public key, and the ciphertext formed based on the desData value agreed upon by the data sender and the data receiver. After the transmission is completed, the data receiver receives the function to be transmitted, and splits and decrypts the transmitted string to obtain the last parameter after the split and decryption. The last parameter includes the symmetric encryption algorithm identifier, the public key, and the ciphertext formed based on the desData value. Due to the adoption of the above technical scheme, the present invention can uniformly encrypt all parameters and complete all parameter encryption at one time. If any parameter is tampered with, the data legality verification will fail and be quickly discovered.
Descriptions
Cyclic redundancy check + timestamp and digital signature encryption are adopted, and symmetric encryption algorithm is adopted. The encryption speed is fast. The number of bytes of ciphertext and plaintext data is similar, which does not affect the efficiency of data transmission. The encryption algorithm involved in the method is not limited to the encryption method, that is, the encryption algorithm is dynamically matched, and the encryption algorithm used for each data transmission can be different, the encryption strength is stronger, and it is not easy to be cracked.
