ABSTRACT:
A proxy server that is inserted between a plurality of network access servers, typically an access points, and an authentication server. When an original authentication request is received by an network access server, the network access server forwards the request to the proxy server which forwards the request to an authentication server. The authentication server then sends the session information to the proxy server which stores the keying material as a dynamic credentials. When the client re-authenticates with one of the plurality of access servers, the re-authentication request is handled by the proxy server using the dynamic credentials. The proxy server may re-authenticate the client using a different method than the method that was originally used. For example, the original authentication may be by Extensible Authentication Protocol-Transport Layer Security (EAP-TLS) and subsequent reauthentications may use Wi-Fi Protected Access (WPA).
