Abstract

The invention provides an encryption and decryption method and system based on software and hardware cooperation, and belongs to the technical field of data security. The method comprises the steps of obtaining user login information of a calling party, carrying out the identity authentication of a user, obtaining a first exchange key factor of a server side, and generating a first exchange key pair locally; calculating according to the first exchange key factor and the first exchange key pair to obtain a first session key, and encrypting a user login application program identification number and a local IP (Internet Protocol) by using the first session key to generate a first data token; and encrypting and returning the first data token to a calling party, and decrypting the first data token successfully by the calling party and then completing a login process to initiate a service request operation. The encryption and decryption system based on software and hardware cooperation is constructed, automatic generation and updating of the secret key are achieved, and data security protection is achieved by combining the advantages of software and hardware encryption.

Description

technical field [0001] The invention relates to the technical field of data security, in particular to an encryption and decryption method and system based on software and hardware cooperation. Background technique [0002] In recent years, various enterprises, public institutions, and state agencies have established their own information centers, and the scale of each information center is constantly expanding, and its status and role are becoming more and more prominent. People gradually pay attention to security issues. Once the system The leakage of key data stored in the background will bring immeasurable losses to the enterprise. Therefore, establishing a comprehensive security mechanism in the information center can effectively prevent illegal data invasion from outside and inside. [0003] From the perspective of technical implementation, there are currently two types of encryption mechanisms: software encryption and hardware encryption. Software encryption is easy...
