Abstract: 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.

Key words: 3GPP UMTS, security architecture, core network, signaling

摘要： 3GPP UMTS网络是第3代移动通信系统的重要组网技术之一。UMTS核心网安全问题还没有受到充分的重视，缺乏完整的安全体系。为此，在3G网络安全分析的基础上，重点关注3G核心网面临的新的安全威胁和防护需求，建立了适用于3GPP UMTS网络的核心网络安全体系，划分了安全平面和安全层次，明确了核心网络安全目标，建立了未来研究的基础框架。
