摘要
随着计算机网络的发展,电子邮件已成为人们网上通信的重要手段;保护电子邮件的安全成为人们关注和研究的重要内容。本文介绍了一个基于DES算法、RSA算法的电子邮件加密系统SEM,详述了SEM的加密过程、解密过程、密钥维护以及几个基本算法的实现思想。
Along with the explosive growth of computer network, Email has become the important communication means. Protecting Email is a new and important subject. This paper introduces a secure electronic mail system (SEM),whose design and implementation are based on DES and RSA algorithms. The procedure of encryption and decryption,the management of secure key and the implementation of some algorithms are described in this thesis.
