Multicast, PIM-SM, ID-based, Security
This paper presents a new secure scheme for Protocol In dependent Multicast Sparse Mode (PIM-SM). PIM is the predominant multicast routing protocol in use on the Inter net today, where members of the multicast group are dis tributed sparsely over a wide area. Security issues are par ticularly important in such multicast routing protocols. In this paper, we propose two ID-based group key manage ment schemes to build a secure PIM-SM multicast routing protocol. With these schemes, the network administrator can manage the secure PIM-SM multicast more efficiently, and the management of groups is made more flexible.
