摘要
对3G用户接入时的认证鉴权进行分析和研究,介绍了3G的安全体系结构,详细分析了3G的认证和鉴权机制和过程、用户信息的加密和完整性保护的过程和方法、密钥协商机制,并指出了3G认证鉴权机制可能存在的缺陷,最后对2G和3G的互通方面的安全性和2G与3G安全上下文之间转换运算的算法进行了分类和剖析。
The authentication and authorization are analyzed and researched when a 3G user is accessed in this paper. The 3G security system architecture is introduced firstly; then the detailed analysis is made about the process of authentication and authorization for 3G, the process and method of encryption and integrity protection for user's information, and the negotiation mechanism of privacy key, at the same time, the potential vulnerabilities of this mechanism is given; and at last, the mutual security and the conversion algorithm of security context for 2G and 3G are classified and anatomized.
