Abstract: For the secure problems existing in current E-mail systems, this paper establishes the mail server which filters the spam and virus, and the gateway server which filters the secret-involved mails. It accomplishes the secure mail client and the manage control center with the technology of identity-based cryptography and content-based filtering. The system can provide safe communications between these enterprise employees who are uncontrollable and dynamic.

Key words: identity-based, public key cryptography, secret-involved scanning, gateway server, secure E-mail

摘要： 针对现有电子邮件系统中的安全性问题，采用基于身份的密码体制和基于内容的过滤扫描技术，构建具有反垃圾/反病毒功能的邮件服务器及具有涉密扫描功能的邮件网关服务器，设计并实现了邮件系统客户端及其必备管理控制中心。系统具有扫描并过滤涉密邮件、加密或解密邮件、签名或认证邮件等功能，能够满足在不可控、动态和松散企业组织成员间的安全通信。
