While a lot of important information is being sent and received on the Internet, the information could be exposed to many threats, and the more the multicast service is various and generalized, the more the service range is widened. When a new member joins in or leaves from the multicast group, the group key, which the existing member used, should be newly updated. The existing method had a problem that the performance was depreciated by the key exchanging. This paper proposes the effective group management mechanism for a secure transmission of the multicast data on the multicast group.
