摘　　要：统一移动通信系统(UMTS)是新的第三代蜂窝移动通信系统的一种。UMTS构建于第二代GSM系统的成功之上。GSM获得成功的一个因素就是其安全特性。UMTS中引入的新型业务需要新的安全特性来保护之。而且,GSM中某些实际的和假想的安全瑕疵要在UMTS中加以解决。本文将对GSM和UMTS认证和安全机制加以阐述和比较分析。The Universal Mobile Telecommunications System （UMTS） is one of the new eothird generationl mobile cellular communication systems. UMTS builds on the success of the eosecond generation GSM system. One of the factors in the success of GSM has been its security features. New services introduced in UMTS require new security features to protect them. In addition, certain real and perceived shortcomings of GSM°°security need to be addressed in UMTS. This paper gives a comparative analysis of authentication and security mechanisms of the two systems.
