Abstract: Abstract: An improved protocol for conference key distribution algorithms is proposed based on the identity-based with fault-tolerant conference key distribution which is put foroard by Yang et al,and the correctness and security of the protocol is analyzed.This method makes the honest participants consult a common conference key even in the presence of malicious participants;and be able to effectively resist passive attacks and active attacks.

Key words: identity-based, fault-tolerant, conference key

摘要: 利用Yang等人的一个基于身份的并且错误容忍的会议密钥分配方案,提出了一种改进的会议密钥分配协议算法,并分析了该协议的正确性和安全性。分析结果表明,该方案不但实现了即使存在恶意参与者的情况下,诚实参与者也能协商出一个共同的会议密钥的目的;而且能够有效地抵抗被动攻击和主动攻击,安全高效,具有很强的实用性。
