Security Architecture of 3GPP UMTS Core Network

UMTS is one of the most important networking technologies of the third generation mobile communication system.Security in UMTS core network is lack of attention,and no integral security architecture is defined.To solve this problem,security of the third generation communication system is analyzed,and security architecture applied to 3GPP UMTS core network is proposed.This architecture provides a basis to security study of 3G core network in future.
