The VLR/SGSN starts this procedure by requesting authentication vector to the HE/AuC. 3G security features. The UMTS World is an 3G mobile system news and information provider. Comprehensive coverage of UMTS / 3G news, licensing, business developments, 3G WCDMA telecommunication technology, multi media mobile phones and future communications. The 3G security is built on the 2G (GSM) Security architecture. The 2G architecture has been proved to be robust and effective. It was hence decided that the 3G security architecture will be based on this.

The 3G security architecture is a set of security Apr 15, 2003 3GPP security objectives.

IV. UMTS SECURITY Design of third generation (3G) was initiated by some organizations like UMTS Forum, European Telecommunications UMTS specification has five security feature groups: Network access security: the set of security features that provide users with secure access to 3G services, and which in particular protect against attacks on the (radio) access link; Based on the Global System for Mobile (GSM) communication standard, UMTS is endorsed by major standards bodies and manufacturers and is the planned standard for mobile users around the world. UMTS (Universal Mobile Telecommunications Service) is a third-generation (3G) broadband, packet-based transmission of text, digitized voice, video, and multimedia at data rates up to 2 megabits per 4. UMTS Security 3G-security is built on the security principles of 2G systems, with improvements and enhancements in certain points in order to provide advanced security services.

3G Security Features (2) User – Mobile Station Authentication The user and the mobile station share a secret key, PIN Secure Services Protect against misuse of services provided by the home network and the serving network Secure Applications Provide security for applications resident on mobile station Fraud Detection UMTS Security: User Identity Confidentiality (IMSI, TMSI & P-TMSI) Prashant Panigrahi September 4, 2009 6 UMTS system uses the same old concept used in GSM and GPRS to protect the user identity over the service link. UMTS is designed to interoperate with GSM networks.

The 3G security is built on the 2G (GSM) Security architecture. The 2G architecture has been proved to be robust and effective. It was hence decided that the 3G security architecture will be based on this. At the same time it was decided that the shortcomings present in the second generation systems will have to be removed.
