The current 3GPP Authentication and Key Agreement protocol (AKA) has some shortcomings such as the bandwidth consumption between visitor serving network and home network, the delay time that incurred from generated authentication vector in home network, waste of storage space in VLR to store authentication vectors and the management of sequence number which needed for synchronization between mobile station and its home network. This paper proposes a new protocol as an extension for the 3GPP AKA to eliminate the 3GPP AKA shortcomings by using temporary security key.
