【摘要】 文中讨论了一个新的安全有效的会议密钥分配协议,该协议适合多个用户通过临时组建的对等网络实现即时安全通信。相对于GDH.2而言,此方案对通信参与者的身份以及传输数据的完整性进行了验证,而且对最后产生的会议密钥进行了确认,以增加很小的计算和通信负荷为代价,安全性能得到了较大的提高。最后,通过一套即时安全通信系统的设计和实现方法证明其可行性。更多还原

【Abstract】 In this paper it introduced a new secure and efficient conference distribution p rotocol that is suitable for exchanging information over an Ad Hoc network. Comp ared with GDH.2, the identity of the participants and the integrality of transmi tted data are verified in the scheme, the final conference key is affirmed. More over, the security of the new protocol is greatly improved at a slight cost in c omputation and communication overheads. Finally, design and realize an instant s ecure communication system based on Ad Hoc network by using the protocol.更多还原
