Security Analysis of WAPI Access Authentication Protocol WAI

The authentication process of wireless local area network authentication and privacy infrastructure, namely, WAI protocol, is researched and analyzed, and the security analysis is made to its the security authentication and key-agreement process by using CK model. The analysis shows that: WAI can realize security attributes such as message integrity, mutual entity authentication, mutual key-control, key confirmation and so on, and it can also statisfy the secure goal of wireless local area network. Thus, it can be used to enhance the security of wireless local area network instead of WEP.
