Authenticated multicast immune to denial-of-service attack
Shouhuai Xu, Ravi S. Sandhu · 2002
Authentication of multicast streams has attracted a lot of attention in the last few years. However, two important issues, namely multicast denial-of-service and access control, have been ignored in previous proposals. In this paper, we propose two Internet Protocol multicast authentication schemes by making use of the multicast tree as an essential authentication mechanism. Our schemes are efficient and immune to multicast denial-of-service attack. They allow the receivers to immediately authenticate the packets regardless of the packet loss characteristics of the underlying network.
