Dynamic cipher authentication system

Abstract

The invention provides a dynamic password authentication system which comprises a system server (1) used for storing system information and identifying an identity password, and an authentication password generator (2) used for generating the identity password. The system server (1) comprises a system interface (11); a system database (13); an authentication module (12) used for reading the user identity password and an additional code submitted by the system interface (11) and customizing different generation modes based on different parameters written by users in the authentication password generator (2). The authentication password generator (2) comprises an identity password register (24), a clock (23), a password generating module (22), a key input module (25) and a display module (21); the authentication password generator (2) adopts the X arithmetic which is the same as the system server (1) to generate the identity password; the X arithmetic can be different in each authentication password generator (2); the identity password is a numeric string.

Description

technical field [0001] The invention relates to a password authentication system, in particular to a dynamic password authentication system. Background technique [0002] With the development of e-commerce, more and more commercial activities take place on the Internet, the security of customer accounts has become an important issue. In traditional network business activities, the client connects to the server from the client, and the server sends identity confirmation information, and the user enters the confirmation information through the keyboard on the client terminal, such as a password composed of numbers or letters, and the confirmation information will be transmitted to the server, and the server will Undergo verification. In such a system, there are great security risks: firstly, because the identity authentication process uses a single fixed password, once the password is known or deciphered by others, it will cause serious consequences to the transaction securit...

AI Technical Summary

Problems solved by technology

Third, for applications that require client programs, Trojans can even modify the application to steal passwords

In this way, there are serious security problems in the identity confirmation of transactions that rely solely on static passwords
