一种基于软件的安全网闸实现技术

A Software-based Implementation Technology of Safety Gate

本文介绍一种低成本的基于软件的安全网闸实现技术,在两个网络之间增加两台普通的计算机并分别添加发送模块或接收模块,这两台计算机分别连接一个网络,两台计算机间以一条直通的网线连接,网络层以私有协议代替IP协议进行通信,达到了硬件网闸的类似效果。基于软件的网闸成本很低,在一些场景可以代替硬件网闸,具有较高的实用价值。

This paper introduces a low-cost software-based security netgap implementation technology.Two ordinary computers are added between the two networks and sending or receiving modules are added respectively.The two computers are connected to a network,and the two computers are connected by a direct network line.The network layer uses private protocol instead of IP protocol to communicate,which achieves the similarity of hardware netgap.Effect.The cost of software-based netgap is very low.In some scenarios,hardware netgap can be replaced,which has high practical value.
