Abstract
A method for reauthentication during client roaming in a wireless network system. The network has at least one access server and a plurality of access points registered with the access server. The method includes receiving a registration request at the access server from a new access point for a roaming client registered with the access server and sending a client's session key to the new access point in a registration reply upon authentication of the registration request. The client's session key is configured for use by the new access point to authenticate the client and establish keys for the client. A method for secure context transfer during client roaming is also disclosed.
