摘要: 针对会话初始协议(SIP)端到端的安全性问题,提出一种基于S/MIME的SIP签名与加密机制,并对其进行设计和实现。该安全机制将S/MIME的功能移植到SIP用户代理,实现对端到端通话中SIP消息体SDP的保护。仿真测试结果表明,该安全性方案具有较高的可行性,可保证SDP的完整性和不可抵赖性,达到了预期的安全效果。

Abstract: In allusion to the problem of Session Initiation Protocol(SIP) E2E security, this paper proposes and realizes a SIP signature and encryption mechanism based on S/MIME. This security mechanism selects a new method which the function of S/MIME is migrated to SIP user Agents, to protect E2E communication user Agents SIP’s message body SDP. Simulation test results prove the high feasibility of this security mechanism, insure the integrality and nonrepudiation, and realize the expected security performance.

Key words: Session Initiation Protocol(SIP), S/MIME, encryption algorithm
