摘要
Security management of group key is becoming a key problem of multicast security. This paper summarizes five kinds of policy of rekeying group key and some of evaluating criteria of rekeying method, then discusses rekeying group key problem based on some current group key management method. Finally,a method to resist preventing rekeying message from transmitting is proposed.
