- 】SIP协议是会话初始协议，因为其自身和应用环境的特点面临着许多安全威胁。论文针对其中一种主要安 全威胁— — 注册劫持，用两种方法实现此种攻击，并实验对带有摘要认证的SIP的注册劫持攻击，最后提出防范注册 劫持攻击的安全机制。-SIP protocol is Session Initiation Protocol, as its own characteristics and application of environment is faced with many security
SIP8
- 目前，会话初始协议(SIP)大部分认证机制只提供了服务器到客户端的认证，H ITI P摘要 认证便是其中的一种。分析了这种机制容易遭受服务器伪装攻击和密码窃取攻击的缺陷，提出了一 种弥补这些缺陷的安全认证机制。试验表明该算法具备较高的效率。-At present, the Session Initiation Protocol (SIP) authentication mechanism most only provide a server to the client authentic
