WCDMA中的鉴权和密钥分配机制

Mechanism of authentication and key agreement in WCDMA

为了满足第三代移动通信安全体系的要求,详细讨论了WCDMA系统中的鉴权和密钥分配机制,从应用的角度分析了具体的算法和参数,如从HE/AuC发送鉴权消息到VLR/SGSN的过程,VLR/SGSN与MS之间相互鉴权、新加密和完整性密钥的建立过程,重同步过程等。

To meet the need for the 3G mobile communication security system, the paper studie the mechanism of authentication and key agreement in WCDMA, analyzing the algorithm and parameters from the application angle, such as in a procedure to distribute authentication information from the HE/AuC to the VLR/SGSN, a procedure to mutually authenticate and establish new cipher and integrity keys between the VLR/SGSN and the MS, and a re-synchronisation procedure, etc.
