摘　　要：针对可认证邮件传递协议CMP1存在的缺陷,提出了改进方案,通过引入密码原语——加密Hash函数,保护了邮件消息的机密性,引入FTP传输方式传送发方和收方的非否认证据,确保公平性的实现,进一步增强协议的鲁棒性。使用拓展的卿-逻辑分析了改进的CMP1协议的安全目标。In response to the flaws of the CMP1 protocol,this paper proposes an improved protocol which adopts a cryptographic primitive-cryptographic Hash function to protect the confidentiality of e-mail message.This proposed protocol uses FTP method to transmit the non-repudiation evidences of origin and receipt,which not only ensures achievement of fairness,but also further enhances the robustness of the protocol.This proposed protocol is verified to satisfy accountability and fairness by utilizing the extended Qing-logic.
