Abstract

Proposals for key management of secure multicast that have been published so far are concentrated on reducing the complexity of communication for rekeying. If a group manager controls several multicast application groups and each of them involves a large number of members, it is important to maintain a set of secret keys as small as possible in order to reduce the group manager's storage for key management. In this paper, we propose a tree-based key management scheme, where the group manager can access keys by computing on the fly, without storing them. Using a concept of ID-based key generation and node bits on the tree, a storage for key management by the group manager can be greatly reduced.
