Abstract

The invention provides an encryption and decryption method and system of terminal data, and relates to encryption techniques in the field of data safety. The encryption and decryption method and system solves the problem that in the prior art, enterprise data stored on a mobile terminal have safety hidden risks. The encryption and decryption method includes the steps: a client receives a private secret key set by a terminal user, the private secrete key set by the terminal user is submitted to a server end, the server end produces a system secret key corresponding to the terminal user and stores the system secret key, when the terminal user carried out data encryption and decryption operations, the client submits the private secret key of the terminal user to the server end, the server end returns to the corresponding system secrete key after the private secrete key passes verification, and the client carries out encryption and decryption operations on data by means of the private secrete key and the corresponding system secrete key.

Description

technical field [0001] The invention relates to encryption technology in the field of data security, in particular to a method and system for encrypting and decrypting terminal data using a symmetric encryption algorithm. Background technique [0002] With the development of the mobile Internet, more and more smart mobile terminals such as mobile phones and tablet computers are used in mobile office and mobile business activities in various industries such as government, public security, banks, and enterprises. Because the confidential information of the enterprise will inevitably be stored on the mobile terminal. The data security of this information is very important to the enterprise and needs to be encrypted and stored. Data encryption is the basis of information security. The so-called data encryption technology refers to converting a piece of information (usually referred to as plaintext) through an encryption key and an encryption function into meaningless ciphertext...
