A Secure Multicast Service Architecture

Multicast implements the communication between many nodes efficiently and more and more multicast applications are deployed in networks.Security is one of the problems that block the progress of multicast application.In previous multicast security solutions,the multicast security management is implemented by the multicast initiator.This paper proposes SMSA(Secure Multicast Service Architecture),which performs the group security management instead of the multicast initiator.SMSA supports many secure multicast groups simultaneously.We describe the details of SMSA and present the experiment results compared with the existing solutions.It is shown that SMSA improves the efficiency of multicast group security management and has a good scalability.
