The invention provides a data processing method, comprising: S1: reading original algorithm data; S2: selecting algorithm data within default range from the original algorithm and obtaining a corresponding encryption parameter by using an encryption algorithm, wherein the encryption parameter comprising at least one of the following: encryption coefficient and encryption vector S3: inserting the encryption parameter into a default position in the original algorithm data to obtain encrypted algorithm data. The invention encrypts the algorithm data, and the encrypted data is similar to the original algorithm data, thereby greatly improving the security of data transmission.
