last hop topology sensitive multicasting key managment
In this paper we study multicast key management. We illustrate the important role that the features of the last hop play in the context of multicast key management. We then propose several schemes to distribute the keys while focusing on the topology of the last hop. We also show the importance of these schemes when considering last hop wireless networks such as 3G networks. Towards this we have also considered the current proposal for multicasting in 3G networks and shown the advantages that would ensue by considering the proposed last hop sensitive key management schemes in such bandwidth constrained networks.
