Secure Multicast Communication Using Group Based Multicast Hierarchy
Secure multicast communication is a significant requirement in emerging applications in adhoc environments like military or public emergency network applications. Membership dynamism is a major challenge in providing complete security in such networks. This paper proposes an efficient Group Based Multicast Hierarchy (GBMH) algorithm for secret multicast communication, in which source nodes used the Secure Ad hoc On Demand Distance Vector (SAODV) protocol is an extension of the AODV protocol. The Secure AODV scheme is based on the assumption that each node possesses certified public keys of all network nodes. The SAODV protocol collects its 1 hop neighbours to form group.
