ABSTRACT:
A method wherein an access point authenticates itself with neighboring access points and establishes secure and mutually authenticated communication channels with its neighboring access points. When an access point learns of a neighboring access point, it initiates an authentication with an authentication server through the neighboring access point. Once access points have mutually authenticated each other, whenever a station authenticates itself with a first access point, the first access point communicates the station's authentication context information, for example session key and session identifier, to each neighboring access point. Thus, when the station roams to a neighboring access point, the neighboring access point presents the station with a reauthentication protocol, for example LEAP reauthentication, and if the reauthentication is successful, communication between the station and the neighboring access point takes place immediately and no new EAP authentication needs to occur.
