摘要
会话发起协议(SIP)简单灵活,便于业务扩展,是使用最广泛的信令协议之一。但是它缺乏有效的安全认证机制,容易受到攻击。分析了SIP可能受到的攻击,对已有安全认证机制进行比较,并提出一种基于公钥的安全认证机制,增强了SIP域内和端到端的安全性。
SIP is one of the most widely used signaling protocols for its simplicity and scalability. However, it lacks of an effective mechanism for security authentication, which makes it vulnerable to attacks. The potential attacks to SIP were analyzed. Some existing security authentication mechanisms were compared. Then, a new security authentication mechanism based on public key was proposed to enhance the local and end-to-end security of SIP.
