随着通信技术的飞速发展,通信系统尤其是第二、三代移动通信系统中的信息安全与通信保密已显得越来越为重要。详细地探讨了第二、三代移动通信系统的安全体制,重点分析了鉴权(认证)与密钥分配、加密与完整性保护的过程及其安全性。同时对2G与3G移动通信系统中相应的安全技术进行了详细的比较与分析。

With the rapid development of communication technology, it has become more and more important that the information security and communication security in the communication systems, especially in the second and third generations of mobile communication systems, have become increasingly important. The security system of the second and third generation mobile communication system is discussed in detail. The process of authentication (authentication) and key distribution, encryption and integrity protection and their security are analyzed emphatically. At the same time, the corresponding security technologies in 2G and 3G mobile communication systems are compared and analyzed in detail.
