Authentication method, system and device based on improved cryptographic algorithm

Abstract

The invention relates to an authentication method, system and device based on an improved cryptographic algorithm, computer equipment and a storage medium. The method comprises the following steps: acquiring target registration biological characteristic information corresponding to a user group identifier by utilizing the user group identifier of a to-be-identified user through a server, identifying the identity of the to-be-identified user according to a comparison result of the target registration biological characteristic information and the biological characteristic information of the to-be-identified user sent by a coded lock, and sending the to-be-identified user to the coded lock after the identity authentication is passed. The authentication passing information is sent to the coded lock, the coded lock receives the information, generates a random key and sends the random key to the server and the mobile terminal of the user to be recognized, and therefore the server can compare the key input by the user and sent by the mobile terminal with the random key, and authority authentication is conducted on the coded lock unlocking authority of the user to be recognized. Compared with a traditional verification mode through a password, the password lock unlocking authority of the user is authenticated by verifying the biological characteristics and the random key of the user, and the authority identification safety is improved.

Description

technical field [0001] The present application relates to the field of security technology, in particular to an authentication method, system, device, computer equipment and storage medium based on an improved cryptographic algorithm. Background technique [0002] Combination lock is a kind of security equipment to protect equipment or information security, so it is very important to improve the security of combination lock. At present, many combination locks only use simple passwords for identity authentication and authority identification. However, the password-based authentication method is too simple, easy to crack, and cannot accurately judge the authenticity of the identity of the unlocker; and the user is easily seen by others during the process of entering the password, which has certain security risks. [0003] Therefore, the current permission identification method has the defect of insufficient security. Contents of the invention [0004] Based on this, it is n...
