Problems solved by technology

[0002] At present, it is generally necessary to encrypt function parameters when transmitting function parameters. However, in the prior art, when encrypting all parameters, it is One by one encryption, not only the process is cumbersome, but also the data is easily tampered in the process of one by one encryption; in addition, because the encryption process is relatively cumbersome, it will also affect the efficiency of data transmission; moreover, most of the algorithms in the encryption process may The same encryption method is adopted, and the encryption strength is not strong enough, so that the encryption algorithm is easy to be cracked, and the data will be changed, etc., resulting in the transmitted data being changed or stolen

Abstract

The invention discloses a function parameter data transmission encryption method, which comprises the following steps of: a function to be transmitted is acquired, and parameters except the last bit in the function are encrypted to obtain a desData value; in the parameter data transmission process, a data sender transmits all parameters of the function based on the last bit parameter of the function, and during transmission, the last bit parameter is spliced and combined to obtain a transmission character string; and after the transmission is finished, a data receiver receives the function tobe transmitted and splits and decrypts the transmission character string to obtain the last bit parameter after split and decryption. All the parameters can be encrypted in a unified mode, and all theparameters are encrypted at a time; cyclic redundancy check + timestamp and digital signature encryption and symmetric encryption algorithms are adopted, so that the encryption speed is high, and thedata transmission efficiency is not influenced; the related encryption algorithm is a symmetric encryption algorithm, random matching is carried out according to an agreed identifier without limitation, the encryption strength is higher, and the encryption algorithm is not easy to crack.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a function parameter data transmission encryption method, system, device and readable storage medium. Background technique [0002] At present, it is generally necessary to encrypt function parameters when transmitting function parameters. However, in the prior art, when encrypting all parameters, they are encrypted one by one. Not only is the process cumbersome, but also The data in the data is easy to be tampered with; in addition, because the encryption process is relatively cumbersome, it will also affect the data transmission efficiency; moreover, most of the algorithms in the encryption process may adopt the same encryption method, and the encryption strength is not strong enough, resulting in encryption The algorithm is easy to be cracked, and then the data will be changed, etc., resulting in the transmitted data being changed or stolen.
