ABSTRACT:
A method and an apparatus for establishing secured roaming among wireless devices are disclosed. In one embodiment, a first access point requests a first ticket from an authentication server and uses that first ticket to establish a first secured session with a wireless station. In response to a second ticket request from the wireless station through the first secured session, the first access point forwards the second ticket request to the authentication server and also relays a resulting second ticket from the authentication server back to the wireless station.
