AN ACCESS AUTHENTICATION METHOD SUITABLE FOR THE WIRE-LINE AND WIRELESS NETWORK

摘要

An access authentication method suitable for wired and wireless networks, comprising pre-establishing a security channel between the authentication server of the access point and the authentication server of the user terminal and performing the authentication process at user terminal and access point. Said authentication process comprising; 1) the access point sends the authentication_activating message; 2) the user terminal sends the authentication server of user terminal request message; 3) the authentication server of the user terminal sends to the user terminal response message; and 4) the authentication is completed. The method of the present invention has solved the existing technical problem of the impossibility for a network user to use one identity to access a plurality of networks, it is applicable to all network environments, meets the requirements for a network user to access a plurality of networks with one identity, and meets the requirement without encryption under some network environment. It has dissolved the need for a strong security association between the access point and the local authentication server, enhanced extensibility, improved the performance, and enhanced security.
