Abstract

The mutual authentication protocols of GSM and IS-41 are computationally efficient and thwart masquerading and eavesdropping. However, these protocols do not support non repudiation of service. In this paper, we propose a simple authentication protocol for Personal Communication Systems emphasizing non-repudiation and play back attack prevention. We extend the core authentication functions of GSM to include a one way function that establishes trust between the Mobile Unit and Visiting Location Register. The protocol is presented using a general notation and semantic, including major message flows.
