Abstract

The invention discloses a database access control method, device and electronic equipment based on public key verification, wherein the method includes: receiving an access application from a user node; matching user permissions according to the received access application; and generating a user node if the matching is passed. A set of public and private keys; log in to the database based on the generated public key. The invention logs into the database through the generated public key, hides the real identity of the user node, can avoid data leakage or attack, and improves data security. Moreover, by using the user public key for identity verification, different users with the same IP The corresponding data reading permission can be obtained, and the situation of insufficient permission or excessive opening will not occur.

Description

technical field [0001] The present invention relates to the technical fields of computer technology and cryptography, in particular to a database access control method, device and electronic equipment based on public key authentication. Background technique [0002] With the advancement of network speed and the rise of the Internet industry, the amount of information received by people is increasing, and the awareness of data sharing is gradually rising, so that the concept of database was born. The emergence of databases is also related to the security considerations of databases. After all, databases often access personal private data or key data of enterprises. The first line of defense of the database lies in the user's access control. There are three main methods of database access control: Discretionary Access Control (DAC), Mandatory Access Control (Mandatory Access Control, MAC), and role-based access control. (Role-Based Access Control, RBAC), and RBAC is more comm...
