Internet与Intranet网间文件安全交换方法研究

Method of Secure File Exchange Between Internet and Intranet

军工企业按照国家相关部门的要求,涉密信息系统必须与国际互联网及其他公共信息网物理隔离。因此这些企业的内部资料外发和外来资料接收,通常要经过复杂的审批、交换流程。为了提高这种网间文件交换管理工作的便捷性及安全性,我们设计了一套"Internet与Intranet网间文件交换系统"。该系统基于B/S模式,采用Java及Sql Server等技术开发,分为内网系统和外网系统两部分。对于其中应用到的"内外网间文件交换"相关技术进行了阐述,给出了实现方法。通过对该系统的运行情况分析,这种文件交换方法在很大程度上解决了军工企业内外网间文件交换的便捷性和安全性之间的矛盾,可以在更多行业内推广应用。

According to the government requirements, the military industrial enterprises must insulate the internet and intranet. So the enterprises must use the complex processes to complete the internal data and external data exchanging. In order to improve the convenience and safety in file exchanging, it designs a file exchanging system between internet and intranet. The system is based on B/S mode,uses Java and SqlServer. The system is divided into two parts： the intranet and internet system. This paper expounds the technology of file exchange between internet and intranet. Through the analysis of the system effect, this method solves the contradiction between safety and convenience . This paper can extend this method to more industries.
