基于ARM的网络隔离器的设计

Design of Network Physical Separator based on ARM

简单介绍了物理隔离及物理隔离技术。构建了一个基于ARM的网络隔离器设计方案。本方案使用双端口RAM通过双通道实时开关技术连接内网和外网,将内外网的双向数据传输转换为两个单向数据传输,从硬件和软件上保证了内外网的安全隔离。

Physical GAP and physical GAP technology is briefly introduced. A design of ARM-based network physical separator is developed. This design use dual-port RAM to connect internal network and external network by dual channel real-time swiwher technology. Bi-directional data transmission between internal network and external network is changed into two unidirectional data transmission, which guarantee security isolation between internal network and external network based on hardware and software.
