CDMA2000通信系统接入安全的研究

Research on Access Security in CDMA2000 Communication System

对CDMA2000通信系统的基本接入认证过程和增强接入认证过程进行了研究,分析了相关的协议与算法及加密的机制和作用原理。通过分析,指出了现存的认证机制面临的安全威胁和存在的安全隐患。介绍了基于公钥的通信机制,证明只有基于公钥的认证方案才能真正满足人们对移动通信日益增长的安全需求。

This paper mlalyses the common access authentication process and the enhanced access authentication process of CDMA2000 system. Then we study the involved protocols,algorithms and their encryption mechanism and operation theories. On these basics, pa- per point out the security threat and hidden trouble,which the existent authentication mechanism faces to. At last paper introduce the mechanism based on the public key structure, prove that only the mechanism based on the public key can satisfy the increasing demand of security in mobile communications.
