Abstract: Session Initiation Protocol(SIP) has played an important role in many fields.As one of the core agreements of the next generation Internet,however,SIP security is to be a crucial issue.In this paper,the existing SIP security mechanisms are analysed,and a new SIP authenticated key agreement mechanism based on Self-Generated-Certificate Public Key Encryption scheme(SGC-PKE) is presented,which assures the integrity,confidentiality and non-repudiation during the transmission of SIP message and overcomes the disadvantage of Public Key Infrastructure(PKI).

Key words: session initiation protocol, self-generated-certificate public key encryption scheme, mutual-authentication, key agreement

摘要: 会话初始协议(SIP)在许多领域已经开始发挥重要的作用。作为下一代互联网中的核心协议之一,SIP实体间通讯的安全性成为了至关重要的问题。通过对SIP现有的安全机制进行分析和比较,在此基础之上提出了一种新的基于自生成证书公钥加密体制(SGC-PKE)的可认证密钥协商方案,保证了SIP消息在传输过程中的完整性和机密性,并克服了使用公钥基础设施(PKI)带来的缺点。
