摘要
SIP协议是NGN中的重要协议,其安全性一直备受人们的关注。然而SIP协议中已存在的安全机制不能完全地确认发起SIP请求的终端用户的身份。首先分析现有的身份认证机制存在的问题,然后介绍一种增强的身份认证管理的设计方案,它能在现在的网络环境中有效地对发起请求的终端用户进行身份认证。
The SIP is an important protocol in NGN,its security has attracted much attention from the people. However,the existing security mechanisms in SIP could not confirm the identity of the sender. This article first analyzes the existing authentication mechanism,and then presents a design scheme of enhanced identity authentication management. This scheme could effectively authenticate the end-user who sends the SIP request message in the present network environment.
