摘要
针对电子邮件在传输过程中存在的安全问题,提出了一种基于三重DES和椭圆曲线密码体制的解决方案。其公钥管理是借鉴PGP系统管理公钥的方法;进而重点介绍了邮件的加密/解密、签名/验证的过程,有效地解决了电子邮件系统中的加密、签名和身份认证问题。
This paper analyzes the security of electronic mail, designs an application scheme based on triple DES and elliptic curve cryptography. And its management of key using the mode in Pretty Good Privacy; then it introduces the method of encryption/decryption, signature/verifying in detail. The system implements message encryption, digital signature and identification effectively in the process of electronic mail delivery.
