一种基于D-H交换算法的电子邮件安全传输方式

An E-mail Secure Transmission Implementation Based on Diffie-Hellman Key Exchange Theory

提出一种基于ESMTP(ExtendedSimpleMailTransferProtocol)和Diffie-Hellman密钥交换的电子邮件安全传输方式,通过交换扩展命令参数,实现了会话密钥的交换,并对密钥计算和缓存技术进行了改进,提高了系统的效率。

In this paper, we propose a secure e-mail transmission implementation based on Diffie-Hellman key exchange theory. Using the user-defined extended command in ESMTP session, the shared security is exchanged in command parameters until compute the session key communication encryption. For efficiency consideration, we also improve on the key calculation and cache technology.
