A first base station which initially receives a service request from a wireless terminal requests authentication information from a central security node and receives in response at least, one, but typically two or more, sets of security information. When it is time for a handoff from the first base station to a second base station, the first base station transmits to the second base station at least one of the sets of security information it received from the central security node. The second base station then uses the information it received from the first base station to authenticate the wireless terminal.
