摘要： A method and a system for network access control are provided, which are based on cipher code mechanism. After a visitor has raised an access request, an access controller in the destination network processes the access request and initiates an authentication request on the visitor identity to an authentication server through the visitor. The access controller in the destination network accomplishes the authentication on the visitor identity according to the public authentication result of the authentication server transferred by the visitor, and performs according to the authorization policy the authorization management on the successfully authenticated visitor. The present invention solves the problem of incapableness of performing the access control when the access controller can not directly use the authentication service provided by the authentication server. The present invention can sufficiently satisfy the real application requirements of access control on visitor.

摘要： The invention involves a method and a system for station (STA) switching when a wireless terminal point (WTP) completes wireless local area network (WLAN) privacy infrastructure (WPI) in a convergent WLAN. The method includes steps as follows. The STA implements re-association rebinding process with a target access controller (AC) over a target WTP. A base key is requested by the target AC from an associated AC. An associated WTP is informed to delete the STA by the associated AC, and the target WTP is informed to add the STA by the target AC. A session key is negotiated based on the requested base key by the STA and the target AC, and is synchronized between the target AC and the target WTP. The method enables fast and safe switching of the STA between WTPs under the control of different controllers in the convergent WLAN based on WAPI protocol.
