摘　　要：电子邮件作为广泛使用的网络工具,在给人们带来方便的同时它的安全性问题也日益突出,于是怎样保证电子邮件的安全性便成了计算机网络技术进一步发展和普及的重要课题。提出了一套完整的安全电子邮件解决方案,包括对电子邮件的数字签名、数据加密以及同CA的接口(支持标准的x.509、PKCS12数字证书以及标准的CRL列表),从而提供了电子邮件的保密性、认证性(认证身份)、完整性和不可抵赖性,有效地解决了传统电子邮件存在的若干安全性问题,使通过电子邮件传送机密信息成为可能。As E-mail is a widely used internet tool which brings more convenience to people, it's security request has been increasing urgently. So how to provide security for E-mail becomes an important task that propels computer network development and popularization. The thesis presents a comprehensive solution for security E-mail, including digital signature and encryption and interface for CA (supporting standard X509, PKCS12 digit certification and standard CRL). This solution provides E-mail confidentiality, authentication, message integrity assurance and undeniableness of origin.
