Abstract

The multicast transmitting the real-time data to groups may easily have many attacks from abnormal attackers because it has many links as compared to the unicast. The existing group key management architectures for preventing these problems are designed for protocols suitable for a large scale. Thus these architectures applied to a small scale routing protocols may have many overheads with key distribution and a constant core tree. Therefore this paper proposes a group key management protocol for a secure multicast in PIM-SM multicast group communication. The proposed method divide multicast groups with RP(Rendezvous-Point), and subgroup key managers are established in each RP and can be transmitted groups keys between senders and receivers, so the security channel is set up for secure data transfer. And this does not have needs of the data translation for group keys and the new key distribution for path change. As a result of this, the data transmission time can be reduced.
