ECC algorithm-based identity authentication system and identity authentication method

Abstract

The invention relates to an ECC algorithm-based identity authentication system and an identity authentication method. The system comprises a client interface, a dynamic password generator, an application terminal, an authentication server, a management system and a database. The system and the method are characterized in that: the client interface is connected with the dynamic password generator; the client interface is connected with the application terminal; the application terminal is connected with the authentication server; the authentication server is connected with the management system; the authentication server is connected with the database; and the management system is connected with the database. The system and the method have the advantages of improving the safety performance of dynamic password identity authentication, improving the verification speed of an authentication center, reducing system space consumption and saving the network bandwidth.

Description

technical field [0001] The invention relates to an identity authentication system and an identity authentication method based on an ECC algorithm. Background technique [0002] Identity authentication is the cornerstone of information security. Before users access any system, they must first pass some kind of identity authentication mechanism to verify whether the user's identity is legal. Only after the identity authentication is successful, can some resources of the system be accessed or an operation be performed according to the legal identity of the user. [0003] The traditional symmetric encryption algorithm to generate a dynamic password requires high confidentiality of the algorithm; the traditional HASH algorithm to generate a dynamic password is irreversible, and some scholars have found the collision of MD5, SHA0 and SHA1, and some HASH algorithms will withdraw from the stage of history . [0004] ECC is an asymmetric public algorithm like the RSA algorithm. It...
