摘　　要：移动通信网络应用范围的不断扩展和新型业务的涌现需要有更多的特殊安全协议来保障其安全性 .YiMu和VijayVaradharajan提出了两种分别应用于同一服务区和不同服务区的端端保密通信协议[1,2 ] .本文首先分析了其不足之处 ,然后设计了同时适用于同一归属局和不同归属局移动用户之间进行保密通信的安全协议 (分别称为域内和域间保密通信协议 ) ,最后 ,分析了上述协议的各项性能 .与原有协议相比 ,本文所提出的协议不仅在安全性和其他性能上有较大改进 。Along with the ceaseless development of application of mobile networks, higher security is required by many jumped-up services of mobile networks, and therefore, sophisticated security protocols for special cases must be designed to fulfill the demand. Two of these are proposed by Yi Mu and Vijay Varadharajan for end-to-end secret communications between two mobile subscribers in same and different service area respectively. We first analyze the defects of them, then we design two new protocols for the same purpose between inter-domain and intra-domain subscribers respectively, and their performance, especially security, is discussed after this. Compared with original ones, ours are improved not only upon security and other performance, but also on universalism and oneness.
