Securing MANET Multicast Using DIPLOMA
Multicast traffic, such as live audio/video streaming, is an important application for Mobile Ad Hoc Networks (MANETs), including those used by militaries and disaster recovery teams. The open nature of multicast, where any receiver can join a multicast group, and any sender can send to a multicast group, makes it an easy vehicle for launching Denial of Service (DoS) attacks in resource-constrained MANETs. In this paper, we extend our previously introduced DIPLOMA architecture to secure multicast traffic. DIPLOMA is a deny-by-default distributed policy enforcement architecture that can protect the end-host services and network bandwidth. DIPLOMA uses capabilities to provide a unified solution for sender and receiver access control to the multicast groups, as well as to limit the bandwidth usage of the multicast group. We have extended common multicast protocols, including ODMRP and PIM-SM, to incorporate DIPLOMA. We have implemented multicast DIPLOMA in Linux, without requiring any ch...
