摘　　要：在互联网技术不断发展的今天,电子邮件由于使用便捷的特点已被人们广泛使用,其安全性显得尤为重要。针对Kim、Koo、Lee所提出的向前保密性电子邮件的安全缺陷,对伪装攻击进行了分析研究,并针对此类攻击引入了带有公钥认证和数字签名技术的相互认证的机制,对电子邮件协议进行了改进,使其获得更高的安全性,并且保持了其运算的高效和完善的向前保密性的特点。As the Internet is increasingly developing today,the e-mail technology is widely used due to its characteristics of convenience and swiftness,and its security issues are of especially important.According to the security flaws of the e-mail protocol with forward secrecy proposed by Kim,Koo and Lee,we did the related analysis and researches on spoofing attacks,and introduced mutual authentication mechanism into the e-mail protocol,which includes the publish key cryptography and the digital signature technology,so that the e-mail protocol has been improved to a higher level of security,and its characteristics of high efficiency and perfect forward secrecy is also guaranteed.

关 键 词：相互认证 电子邮件协议 伪装攻击 完善的向前保密性
