摘要

针对SIP（会话初始协议）认证机制的不足和消息的伪装发送

文章分析了SIP的HTTP（超文本传送协议）摘要认证过程

提出了一种改进的基于hash（散列）运算的SIP双向动态密钥认证机制。该机制利用动态会话密钥协商机制

实现了服务方和客户方的双向认证

同时能为后续的SIP消息传输提供一次事务一次密钥认证机制功能。安全性分析表明

该机制提高了协议的认证安全性

能防止注册攻击和伪装消息发送

确保数据来源的不可否认性。

Abstract

In view of the deficiencies of the Session Initiation Protocol（SIP）-based authentication mechanism and forgery attacks

this paper proposes an improved hash algorithm-based SIP authentication mechanism

which realizes the mutual authentication between the user and the server using a dynamic key negotiation mechanism and provides one key authentication function in one transaction.The security analysis shows that this mechanism improves the protocol authentication security

prevents the replay attack

forgery attack and ensures the non-repudiation of the data sources.
