摘　　要：目前人们频繁地使用移动通信进行信息交流,通信系统中信息的安全性以及网络资源使用的安全性将变得越来越重要。着重研究了移动通信系统的安全。首先对3G安全体系机构作了详细的分析,概述了3G的安全威胁,安全原则、目标和要求,分析了3G的安全特征,对3G接入网络中的认证和密钥协商、数据机密性服务、数据完整性服务等机制进行了探讨。然后,对3G加密算法KASUMI算法作了研究,详细介绍了算法的原理和构成,并对KASUMI算法进行了程序仿真。In this paper,it first analyzes and studies the security architecture of the 3G mobile communication system. It covers the security menaces faced by 3G, the security principles, objectives and requirements. It also analyzes the security features of 3G.Discussion is focused on the authentication and key agreement used in 3G＇ s access network, and the mechanisms adopted for providing data encryption service and dada integrity service. The algorithms and protocols used to implement the above mechanisms are introduced. A study of the standard ;3G encryption algorithm -KASUMI is also made in this thesis. Detailed discussion is focused on the principles and structure of KASUMI algorithm.
