| 摘 要： | 移动终端通过通用分组无线业务 (GPRS)接入IP多媒体子系统(IMS)时，GPRS和IMS都会对移动终端进行认证和密钥分配，操作过程类似，独立进行两次，缺乏效率。为解决该问题，结合相关研究成果，提出一种优化集成方法，可以只进行GPRS的AKA协议操作，IMS基于GPRS的认证结果实现对移动终端的认证，同时满足移动终端对IMS网络的认证需求及双方的密钥分配需求。对该方法的可行性及性能进行了分析。

| Abstract: | When mobile station(MS) accesses into IP multimedia core network subsystem(IMS) through general packet radio service(GPRS),the MS should perform authentication and key distribution operations in protocol authentication and key agreement(AKA) at both GPRS and IMS level.The two operations are very similar,so it is very inefficient to perform twice independently.To solve the problem,an optimized integrated scheme based on some previous work is proposed,in which only GPRS AKA operation is performed and IMS can authenticate MS using the result of GPRS authentication.At the same time,the scheme can meet the requirements of MS authenticating IMS and key distribution.Feasibility and performance is analyzed. |
