摘　　要：随着网络和通信技术的飞速发展,信息安全的地位日益重要。作为重要沟通方式的电子邮件系统因会涉及到敏感数据,其安全性研究尤为迫切。基于PKI密钥管理体系,以数字证书为基本认证要素,以角色访问控制为手段,采用数字签名和摘要算法等信息加密技术来实现电子邮件的传输和存储,并且能够验证发件人的身份以确保邮件信息的完整性和不可否认性,对邮件系统进行全面的安全保护,提供安全、可控、便捷的涉密信息传输服务。With the rapid development of network and communication technology, the status of information security is becoming more and more important. As an important way of communication, e-mail system is very urgent because of the sensitive data involved. The digital certificate is basic authentication element in secure e-mail system based on PKI key management system. Introducing digital envelope, digital signature and the algorithm of information encryption technologyrealizes the e-mail encrypted transmission and encrypted storage. And it can verify the identity of the senderto ensure the non-repudiation of the content in mail andprovide a safe, controllable and convenient services classified information transmission.
