Guap-A strong user authentication protocol for GSM

Abstract

Traditionally, the authentication protocols for cellular phone networks have been designed for device authentication rather than user authentication, which brings limitations and restrictions on the functionality of the system. In this thesis we propose a user authentication protocol for GSM (Global System for Mobile) based cellular phone networks. Our protocol permits the use of weak secrets (e.g. passwords or PINs) for authentication and provides certain flexibilities for GSM users. The simulation results on currently established user authentication protocols and GUAP are presented. Our proposal also has a capture resilience extension to disable captured cellular phones securely.
