Abstract

Recently, the research focus of multicast has been put on overlay multicast In overlay multicast, while the multicast routing, data replication and group management have been extensively studied, an important but less studied problem is security In particular, adding confidentiality to overlay multicast is needed To achieve confidentiality, data encryption keys are shared among the multicast group members There is a need for key distribution scheme to solve the rekeying overhead We introduce the key management solution called KTOM And, we propose the use of periodic batch rekeying in KTOM.
