Abstract

This chapter analyzes the security architecture designed for the protection of the universal mobile telecommunication system (UMTS). This architecture is built on the security principles of second generation (2G) systems with improvements and enhancements in certain points in order to provide advanced security services. The main objective of the third generation (3G) security architecture is to ensure that all information generated by or relating to a user, as well as the resources and services provided by the serving network and the home environment are adequately protected against misuse or misappropriation. Based on the carried analysis the critical points of the 3G security architecture, which might cause network and service vulnerability are identified. In addition, the current research on the UMTS security and the proposed enhancements that aim at improving the UMTS security architecture are briefly presented and analyzed.
