摘要
SIP协议正成为VoIP通信的主流协议之一。面对复杂、开放的Internet应用环境,SIP协议的安全性有待于进一步改进和提高。文中全面分析了SIP协议面临的安全威胁,并通过模拟攻击实验进行验证,最后提出了其认证机制的改进方法,并部署安全SIP解决方案。
With the widespread use of multimedia communications, SIP（Session Initiation Protocol） is becoming one of the most important protocols in the VolP field. Facing the complex and open Interact environment, the security of SIP needs to be improved and enhanced. This paper analyzed the security threats to SIP at first, and then proved the existence of these threats by simulated attacking experiments, finally improved the authentication mechanism and provided security solution to SIP.
