Abstract

The invention provides a data encryption method and system. The method comprises the following steps: a server receives a data packet sent by a terminal and obtains the data type information in the data packet; the server determines a corresponding encryption algorithm and uses the encryption algorithm to encrypt the data packet according to the obtained data types, algorithm security levels and an algorithm name table; the server counts the illegal cracking ratios of data packets corresponding to all data types within a preset period and redefines a target encryption algorithm for all data types according to the data types, the range of cracking ratio and an algorithm adjustment strategy table. The data encryption method and system provided by the invention realize the technical scheme that the algorithm is adjusted according to the algorithm cracking ratio, and further ensures the data communication security.

Description

technical field [0001] The invention belongs to the field of intelligent control, in particular to a data encryption method and system. Background technique [0002] The prior art discloses a method and system for preventing illegal connections. The above method includes the following steps: the server obtains an algorithm from the list of encryption algorithms according to a preset policy as a preprocessing encryption algorithm, and sends the information of the preprocessing encryption algorithm to the client; after the client receives the information of the preprocessing encryption algorithm, it obtains And call the preprocessing encryption algorithm to encrypt the plaintext to obtain the ciphertext, and send the ciphertext to the server; after the server receives the ciphertext, call the preprocessing encryption algorithm to decrypt the ciphertext, if the decrypted plaintext is consistent with the plaintext stored in the server, the server Call the preprocessing encrypti...
