System and method of dynamic password identification

Abstract

This invention discloses a network dynamic password authentication system, which includes a network login server and a dynamic password authentication server, the network login server at least including the password configuration module, used to obtain the user's dynamic password expression according to the dynamic password parameters agreed in the password configuration module; the dynamic password authentication server uses the dynamic password expression to generate the current dynamic password and compare with login information by user input for authentication. The invention also disclosesa network dynamic password authentication method, the method including: a. access to the user login information; b. generate the current dynamic password; c. compare the user input login informationwith the current login dynamic password, if consistent, passing the authentication. The system and method can effectively prevent the user password from the disclosure, such as theft, interception, guessing or Trojan computer virus record, etc., and it enhances user security.

Description

technical field [0001] The invention relates to the field of AAA with Authentication, Authorization and Administration as the core, in particular to a dynamic password authentication system and method suitable for networks. Background technique [0002] With the development of network technology and the popularization of the Internet, people's activities based on the Internet or network are increasing, and the identification of network users is becoming more and more important. At present, the password setting method of most application systems basically adopts a static password, that is, if the user does not change the password, there will be no change in the password. This password is vulnerable to retransmission attacks during transmission on the Internet. Long-term use will cause security risks such as theft, interception, and guessing. In order to solve the above security problems, there are three other password authentication methods different from the above static pa...

AI Technical Summary

Problems solved by technology

Although this method solves the problems caused by method (1) and method (2), the software token in this method can only be logged in on a specific client that has installed the software, and users cannot use their tokens anytime, anywhere. account, which has caused a great obstacle to the immediacy of user use

Moreover, users cannot set the complexity of passwords according to their own needs, which affects the flexibility of users.
