构筑IPv6协议下的安全邮件系统

Construction of Secured E-mail System Based on IPv6

在分析PGP协议和IPsec协议的基础上,提出一种安全邮件系统的基本结构,并对邮件传输流程进行分析,初步实现了邮件在IPv6环境下发送、接收、加密、解密、签名、验证等功能。同时,系统融合了PGP的密钥证书管理功能,为电子邮件用户提供端到端的安全服务,实现了邮件在传输过程中的保密性、完整性、发送方和接收方身份认证以及不可否认性等。

The essential structure of a kind of secured E-mail system based on PGP and IPv6 protocol is put forward.The transport process of E-mail is analyzed. The function of sending, receiving, encrypting, decrypting,signing,verifying e-mail based on IPv6 is essentially realized.The system also inorporates the function about the management of security key certification of PGP.It provides the email users end-to-end security services, realizes security such as confidentiality, integrity, deliver and receiver identification and non-reputation during the transferring process of e-mail.
