摘　　要：基于IP组播路由协议存在的安全问题,深入剖析了多种针对组播网络的DoS攻击行为,总结了三类组播DoS攻击模式,进而设计并实现了一个组播安全的主动测试框架以评估IP组播网络安全.通过主动测试,可以发现组播路由协议以及组播部署中存在的安全隐患,帮助运营商及早发现和解决组播安全问题.As an efficient group communication method,which is different from IP unicasting,IP multicasting works as a network infrastucture.IP multicast network is facing many security menaces.Based on the securlity problems of multicast routing protocol,this paper deeply analyses a few multicast DoS attack behaviors,and presents three multicast DoS attack patterns.A multicast security aggressive test framework is designed and implemented to assess the security of IP multicast network,and help operators and manufacturers find and solve the problem of its security as early as possible.
