摘　　要：集中式的组播授权策略采用组控制器加强对安全组成员的管理,并通过授权表实现对组成员的统一授权,使得只有通过授权的参与者才能具有与安全组成员的安全通信能力,授权表和安全组的动态更新与分发,有效地支持前向加密、后向加密和抗同谋破解。In order to manage members of secure multicast, this paper proposes a centralized warrant scheme. The scheme sets a warrant table by a group controller, each record of warrant table defining a secure group. After group controller partitioning all members into different secure group, members can communicate securely with other members in same secure group. It can support forward confidentiality, backward confidentiality and anti-allied attack by dynamically updating warrant table and secure group.
