Abstract A new key management scheme applied for large dynamic multicast group is proposed in this paper. In the hierarchical structure one-way hash chain is used as transmission key to transmit the data between the levels. Digital envelope is used to realize key management in subgroups. This scheme is of good attributes in computation, storage and dynamic security. It provides a valuable reference to further study.

Key words： Group key management One-way hash function Digital envelope
