摘要: 针对独立无关组设计了一种新型的安全组播密钥管理协议。该协议不需要一个专门的组控制器集中管理,采用二叉密钥分配树完成组密钥更新机制,实现了组成员加入敏感性和离开敏感性组密钥更新策略,组成员之间使用基于身份标识的密钥共识协议完成相互认证,有效地抵抗中间人攻击,并且解决了传统方式用公钥证书认证所引起的带宽消耗和计算耗费问题,保证组播通信的安全性和高效性。

Abstract: This paper introduces a new family of protocol addressing collaborative group key agreement for secure group communication in autonomous groups.The protocol uses a concept of implicitly-certified public keys to achieve higher efficiency based on the unique identification. The protocol can be used for autonomous group key agreement where no central server is necessary and no member has a special role.
