安全组播综述

A Survey of Secure Multicast

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 ,但是组播的安全问题却阻碍了组播技术的广泛使用 .文章首先讨论了组播所面临的安全风险 ,解释安全风险产生的原因 ,并归纳总结组播的安全问题 ;然后对其中两个需要迫切解决的安全问题的解决方案进行深入的论述 。

Multicast protocols provide a mechanism for a sender to send a message to multiple receivers simultaneously, but the security of multicast hinders the wider deployment of multicast. In this paper, we first discuss specific threats that are relevant to multicast, and explain why they are so, and summarize the security issues of multicast; then discuss the solutions to two security problems urgent to be solved in depth, analyze and evaluate these solutions.
