Formal Analysis of A Novel Mutual Authentication and Key Agreement Protocol

Abstract

This research work analyzes the universal mobile telecommunication system (UMTS) authentication and key agreement (AKA) protocol, which suffers from the traffic bottleneck at home location register and authentication center (HLR/AuC). In addition, serving network has no capability to authenticate mobile station. To overcome these problems a new security scheme has been proposed which provides a more efficient and a secure authentication between mobile station and home networks, the proposed protocol called Efficient AKA (E-AKA). The E-AKA uses a temporary key to enable visitor location register and serving network (VLR/SN) to authenticate mobile station (MS) without intervention of HLR/AuC. To analyze and validate the security of the proposed protocol, the BAN (Burrows, Abadi and Needham) logic is used. The results show that the E-AKA protocol is more robust than the current AKA protocol.
