Abstract  Abstract

A novel key management approach is provided for securing communication handoffs between a UE and two base stations. A UE establishes a secure communication session with a first base station based on a first master session key based on a master transient key. The UE obtains a second base station identifier associated with a second base station and sends a message associated with a handoff to either the first base station or the second base station. The UE generates a second master session key based on at least the master transient key and the second base station identifier. The second master session key is used for secure communications with the second base station in connection with an intra-authenticator handoff from the first base station to the second base station. The UE then moves the secure communication session to the second base station.
