摘要
提出一种Byzantine故障环境下的安全群组通信方案.在安全群组通信的通信安全层中引入Byzantine协议,采用Byzantine机制在组成员间达成一致的意见,从而检测出叛变者.在忠诚的组成员之间进行密钥协商,从而能够保证在组密钥协商之前参与协商的群组成员不是叛变者.与以前方案相比,该方案在通信开销与计算开销都有所增加,但是它能够防御内部攻击,提高了安全性及具有容忍入侵性.
Secure group communication scheme in Byzantine failure environment was developed to improve the poor security and intrusion tolerant of most existing secure group communication.Byzantine protocol was introduced in communication security layer..All loyal group members decide on the same plan of action in order to detect traitor by adopted Byzantine mechanism.That group key agreement was completed among all loyal group member make sure group member was not traitor before group key agreement.Compared with previous secure group communication system,this scheme dealt with insider attacks,but it added communication and computation costs.
