基于PKI的SIP协议安全的研究

A Study of PKI-based SIP Security Based on PKI

IETF 提/P 协议安全解决方法,通过使用基于数字证书的认证和加密机制,解决了 SIP 协议进行会话呼叫控制时的安全问题,为 SIP 协议在网络上的应用奠定了安全基础。

SIP (Session Initiation Protocol) is a signaling protocol on the IP network . In the application of SIP, it is crucial to ensure its security during the course of communication in SIP. This paper introduces a solution based on PKI(Public Key Infrastructure), which solves the security problems of the SIP and ensures the SIP applications over the internet.
