摘要 组播提供了一种发送者同时发送信息到多个接收者的高效通信机制。源认证是组播通信系统的重要安全问题,接收方在验证了消息来源后方可接收消息。本文分析了现有的两类源认证后,提出了一种基于CA的安全组播源认证新方案。 Mulficast protocols provide a mechanism for a sender sending messages to multiple receivers simultaneously. Source authentication of the message is an important problem in security multicast system. Receivers must authenticate the source of the message before it can be accepted. This paper presents a new CA-based source authentication sclmme in security multicast after analyzing two kinds of source authentication solution presented.
