| 摘 要： | 针对会话初始协议（SIP）的典型安全威胁，提出了基于强认证技术的SIP安全认证模型，并分析了其安全性。该认证模型通过智能卡和数字证书的强组合实现强认证，并据此对SIP做出相应扩展，将强认证技术有机地融入到SIP协议当中，实现了会话双方的安全认证，保证了SIP消息传输的机密性、真实性、完整性和不可否认性，从而提高了SIP的安全性。

| Abstract: | With regard to the representative security threats to SIP, Session Initiation Protocol(SIP) secure authentication model based on strong authentication technology was put forward, and its security was analyzed. The authentication model achieves strong authentication by combining smart card with digital certificate, extends SIP accordingly, and imports strong authentication technology into SIP. The model implements the duplex secure authentication of session, and ensures the confidentiality, authenticity, integrality and undeniability of SIP message transportation. As a result, it improves the security of SIP. |
