Abstract

The system consists of smart card for generating one time password (OTP), device for creating OTP, authentication server, windows fault-tolerance authentication and synchronization method. The personal ID information and OTP are transmitted to authentication system through network. The authentication system selects one or more possible examining passwords from a large group of examining passwords to build up a smaller group of examining password. The received OTP is compared with the smaller group of examining password; if the OTP is in the smaller group the authentication of the use is passed.

Description

technical field

[0001] The invention relates to a technology for generating a dynamic password based on a smart card, in particular to an authentication method for identifying user identities in computer and network communication systems using the technology. Background technique

[0002] In today's world, the application of information systems has reached the state of ubiquity. Almost any organization needs to use various communication networks for its internal employees and external customers to obtain various services provided by its application systems. Therefore, how to Confirming the identity of the user becomes a crucial issue.

[0003] In the network communication environment, unlike traditional face-to-face communication, people can no longer use ID cards, seals, signatures and other physical tokens to confirm the user's identity. Therefore, a method of agreeing a set of personal identification code (PIN) and password (PASSWORD) in advance b...
