With the improvement of wireless network, there are increasing users wirelessly accessing the Internet through mobile phones. So it is very important to solve the identity authentication problems of wireless access users. Dynamic password has become the new development trend for the Identity Authentication mechanism. It offers stronger security than the static password. In this article, a dynamic password authentication protocol based on callenge/rsponse mechanism is designed. According to this protocol, a dynamic password identity authentication system based on mobile phone token is designed. The composition and authentication processes of this system are described in detail, and its security is analyzed as wel1. The analysis indicates that this system features high security and wide application. It can be conveniently used and implemented in low cost.
