摘要
VoIP系统是一项通过IP网络数据包传送语音的通信业务,保证VoIP的安全是提供IP通信业务的前提,而身份认证则是IP网络安全体制中最为重要的环节之一.随着SIP正成为VoIP通信系统的主流协议,文章在总结了当前VoIP系统对呼叫者身份进行认证的方法的基础上,提出了一种基于智能卡和SIP来电ID的双因素身份认证技术解决方案,并通过模拟攻击实验,对其安全性进行了分析.
VoIP system is a communication transaction that transported voice by wrapped IP packets, the premise of proriding IP communication service is to guarantee its security. Authentication plays one of the most important role in IP network security mechanism. As IP is becoming the most essential protocol in VoIP field, the ways of authentication applied in present VoIP systems are summarized and a new solution is put forward in this paper, it is a kind of double-factor authentication technology that based on smart card and SIP caller-ID. Its security was analyzed by simulated attacking experiments.
