摘　　要：伴随着VOIP的广泛使用,SIP协议以其简单、易于扩展、便于实现等诸多优点已受到越来越多的人青睐,但SIP面临的安全威胁以及SIP安全机制的现状又令人不得不警觉。文中针对SIP协议的安全性设计并实现了完整性的解决方案,并分别采用SHA-1/MD5加密算法对SIP协议进行加密生成摘要相比较的方法来实现完整性;对使用SHA-1/MD5的算法在不同的硬件配置下实现完整性进行了性能分析和性能测试。With the wide use of VOIP, SIP is increasingly popular because of its simpleness, extendibility, and easy implementation. However, the present situation of security threat and mechanism faced by SIP are concerned.The thesis aims at the security design and implements the integrity solution. With encrypting algorithm of SHA-I/MD5 and by cyption-created digest comparison of SIP, the integrity is implemented. At the same time, the capability analysis and performance test of integrity implementation under different algorithms and different hardware configurations by SHA-1/MD5 is carried out. The experiment indicates that the integrity scheme could run well,has general-use features and could be widely applied.
