Dynamic cipher authentication system

Abstract

The invention provides a password authentication system which comprises a system server (1) used for storing the system information and carrying out identification password authentication and an authentication password generator (2) used for generating an identification password. The system server (1) comprises a system interface (11) and a system database (13), an authentication module (12) used for reading the user identification password and the additional code submitted by the system interface (11) and customizing different generating modes by the written parameters in the authentication password generator (2). The authentication password generator (2) comprises an identification 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 identification password; the X arithmetic can be different in each authentication password generator (2); the identification 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 business activities are taking place on the Internet, and 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 out identity confirmation information. The user enters the confirmation information through the keyboard at the client, such as a password composed of numbers or letters. The confirmation information will be transmitted to the server. Undergo verification. In such a system, there are greater 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 for transaction security. Secondly, network viruses are...
