基于PKI的安全电子邮件系统的研究及实现

Research and realization of a secure E-mail system based on PKI

针对企业内部网中电子邮件传输过程中出现的安全性问题,基于公钥基础设施(PKI),综合运用加密、RSA数字签名、指定验证者签名、公钥证书及认证技术,实现了电子邮件在传输过程中的保密性、完整性、不可否认性;基于B/S模式,开发了邮件加解密、数字签名服务的电子邮件客户端程序。

Aiming at the problems of transforming E-mail in enterprise network,a PKI-based security solution was put forward with the help of comprehensive utilization of data encryption,RSA digital signature ,designated verifier signature,public key certificate and authentication technique to solve a series of security problems such as privacy ,integrality,and undeniability and so on. A client program with E-mail encryption and digital signature functions in B/S mode is developed.
