【摘要】 组播业务的实施离不开组播安全。文中提出了一种使用会话初始化协议(SIP)作为信令实现安全组播的方法,该方法利用SIP协议身份验证机制、S/MIME加密与签名、会话参数协商能力,提供了组播源和接收者访问控制、组播源认证以及安全通信。该方法具有安全性高、运行稳定、扩展性好的优点,并能轻松移植到IPv6下运行。更多还原

【Abstract】 Deployment of multicast service requires multicast security.In this paper,propose a way of secure multicast based on SIP.By the mechanism of authentication,S/MIME and session parameters negotiation supported by SIP,multicast sender and receiver access control,source authentication and secure communication are acquired.This method has the advantages of high-degree security,stable operation and good performance of expansion,and can easily be transferred to run under IPv6.更多还原
