| Abstract(in English) | Secure multicast is a technology to achieve confidentiality of messages in multicast communication. To realize secure multicast, it is necessary to share a single key among all members in multicast group. Some proposals for achieving efficient key sharing adopt key hierarchy and reduce the load on a key server. Even with this hierarchical key structure, in multicast groups with frequent change of member, using a single key server for key sharing leads to concentration of the load of key management. In this paper we propose a key management method with network support, where, key management nodes inside a network manage re-keying for receivers nearby itself. Introduction of network support to key management prevents concentration of key management load to a single server. Our simulation results show that our proposal achieves distribution of key management load among key management nodes, and reduces the network stress and the load on receivers for re-keying. |
