MSSIP: A New Secure Multicast Architecture Based on SIP

In this paper, we propose the multicast security based on session initial protocol (MSSIP), which introduces the IETF session initial protocol (SIP) into the multicast security model, to achieve source and receiver access control, source authentication and secure communication. By the multicast control servers (MCS) deployed on the edge of a core network, the MSSIP offers a scaleable and extensible secure multicast architecture for multicast service. After describing the MSSIP architecture, we analyze rekeying performance of the MSSIP. Besides the high scalability of deployment, the MSSIP provides three more methods to manage the scalability: area MCS cluster, physical area division and logical area division
