Security in Multicast Routing in Ad Hoc Network

In recent years, secure communications have become a important subject of research. The new service for wireless and wired networks is to provide confidentiality, authentication, authorization and data integrity. Security has always been a sensitive issue. In fact, this service becomes necessary to protect basic applications, especially E-commerce and bank transactions from a variety of attacks. Ad hoc networks are peer to peer, autonomous networks comprised of wireless mobile devices. The ease and speed of deployment of these networks makes them ideal for battlefield communications, disaster recovery and other such applications where fixed infrastructure is not readily available. limited bandwidth, energy constraints and unpredictable network topologies pose difficult problems for the design of applications for these networks. The last couple of years have seen renewed research in this field. Specifically in unicast and multicast routing and security issues. In this paper, we address how secure the multicast routing problem for ad hoc networks.
