A New Approach to Anonymous Multicast Routing in Ad Hoc Networks

Anonymity in ad hoc network routing came as a means to hide the identification information of nodes, traffic, paths and network topology, which is an effective counter-attack measure to a number of attacks such as traffic analysis, spoofing and denial of services. In this paper, we propose AMUR, an anonymous multicast routing protocol, for ad hoc networks. AMUR uses Bloom filters to encode source multicast tree in each multicast packet to provide anonymity of nodes, links, routing tables, and source routing trees for multicast purposes. We specify the AMUR protocols, and investigate its robustness against network mobility and various attacks.
