키 트리 방식의 그룹 키 관리 성능분석을 위한 시뮬레이터 구현

Group key management protocol plays an essential role to provide data security in multicast. Since bandwidth is a limited resource, it is important to reduce the number of rekeying messages for distributing a new group key. In this paper, we implement the simulator to analyze the performance of group key management protocol and verify the accuracy of the simulator.
