TD-SCDMA空中接口用户数据的加密功能研究

Study on Subscriber Data Encryption of TD-SCDMA Air Interface

安全模式控制(SMC)是一种空中接口安全控制过程。他主要用来在移动通信网络中保证数据的安全性和完整性。主要对TD-SCDMA标准中Uu接口所使用的安全模式控制和其用户数据加密功能及相关过程进行了分析研究,特别对用户数据加密功能进行了着重分析,对其在重定位过程中的实现进行了描述,并分别阐明了源RNC和目标RNC的处理策略。

Securlty Mode Control （SMC） is a security control process of air interface. It is used for guaranting the security and integrity of data in mobile communication network. Analysis and study have been done on the SMC in Uu interface of TD - SCDMA standard and its subscriber data encryptlon function and related process. Subscriber data encryption function is ana- lyzed in details,especially its realization in the re -allocation process. And the handling policy of source RNC and object RNC is elaborated.
