1 终端安全特性的实现概述在 TD-SCDMA 系统中,终端接入网的安全性能主要有三个方面的措施:用户鉴权、数据完整性保护和数据加密。终端安全特性的启动是由网络通知的。其中,鉴权过程是在非接入层的 MM 或 GMM 实现,用于确定用户的合法性。同时产生接入层完整性保护和加密所需要的密钥。数据加密分为语音业务的加密和数据业务的加密,
1 terminal security features Overview In TD-SCDMA system, the terminal access network security performance mainly in three ways: user authentication, data integrity protection and data encryption. Terminal security features are activated by the network. Among them, the authentication process is non-access layer MM or GMM implementation, used to determine the user’s legitimacy. At the same time generate access layer integrity protection and encryption keys required. Data encryption is divided into voice services and data encryption business encryption,
