一种物理隔离数据交换系统的设计

Design of a physical isolation data exchange system

使用安全隔离与信息交换系统对外网和内网进行物理隔离是电子政务建设的重要条件,阻止黑客攻击,预防上网终端机密信息泄漏已成为信息安全领域研究的课题。为确保信息系统的安全,在所要保护的网络数据通道上,建立了一个独立的物理隔离数据交换系统,重点介绍了各部分硬件电路的设计以及软件模块的设计,该系统成功完成了对内外网络的隔离,有很高的实用价值。

Physical isolation, in the way of safety isolation and information exchange system, is the prerequisite of building e-government, stopping the attack of hackers and preventing the information leak from on-line terminals have become the important task in the field of information security. In order to ensure the net security, a physical isolation data exchange system is designed and installed on the data collection system and transmission passage between core networks. This paper mainly introduces the design of hardware and software modules of system. The system isolates internal network and external network successfully and has more practicality.
