由于域内大量敏感信息的存在,企业内部电子邮件系统的安全性受到大量企业管理者的重视。在对现有各种安全电子邮件解决方案进行分析的基础上,指出了现有方案的不足之处。针对存在的问题,充分利用保留格式加密(FPE)技术加密后数据格式和长度不变的特点,在保证邮件协议能正常使用的前提下,对邮件头部信息进行了有效的安全保护,提出了一种基于Feistel网络FPE算法的安全邮件解决方案,使得在保障企业内部电子邮件服务器端和客户端安全性的同时,传输邮件的效率和安全同样获得了保证。
Because there are a lot of secret information in Intranet,electronic mail system security has gained a lot of attention to enterprise managers. Based on analysis of the existing solutions of security e-mail,point out the deficiencies of the existing scheme.

Under the premise of ensuring mail protocol to proper use,mail header information is get for effective protection,and a security mail solution is put forward based on the Feistel networks FPE algorithm. While it ensures the security of enterprise internal e-mail server and client,the efficiency and safety of transmission mail is also received assurance.
