Abstract

The present invention provides a method and a system for authentication and key negotiation in the WLAN Authentication and Privacy Infrastructure (WAPI), in which an authentication organization is included. The method has two steps. Firstly, a client end and / or an access point apply for a self-verified public key certificate from the authentication organization; and secondly, the identity verification and key negotiation is carried out between the client end and the access point by utilizing the self-verified public key certificate. By the present invention, the quantity of data transmission and on-line calculation is reduced, the security of the authentication sytem is enhanced, and problems exist in the course of identity authentication and key negotiation in the WLAN Authentication and Privacy Infrastructure (WAPI), thus further increasing the security intensity of the WAPI authentication mechanism.
