%X The absence of security mechanism has limited the use of multicast. Key management for multicast is used for group members in one multicast session to generate, refresh and transfer keys which are used for encryption and authentication. In addition to the maintenance of keys, issues about scalability, reliability and robustness should be carefully considered. In this paper, the existing problems in key management for multicast are analyzed, and some typical schemes are reviewed.
