摘要
研究了3G的安全特征,分析了从3GPP R99到R5协议版本中WCDMA系统安全机制的发展,通过分析WCDMA R99信令系统中安全机制的建立过程,重点对WCDMA R99网络中的鉴权和密钥协商机制、身份和数据保密性服务、数据完整性服务等机制进行了深入探讨,并对实现上述各种机制的算法和协议做了详细描述。
The development of security features from WCDMA R99 to R5 are researched. Through analysis on the security set-up procedure in WCDMA R99 signaling system, authentication and key agreement mechanism, confidenfiality of user identity and data, integrality protection are discussed deeply. Also the arithmetic and protocol for realizing them are described in detail.
