DT860内外网硬件隔离安全终端的设计与研制

DT860内外网硬件隔离桌面安全终端一体机通过自主研发一块资源连接卡,将经过电路改造后的2块成品主板连接在一起,并配置相应的硬件资源形成2套独立的内外网隔离主机系统,满足了国家电网公司"双网硬件隔离"办公用机的安全需要。与传统的"双网隔离"机相比,它采用硬件隔离安全性访问、瞬时切换、直立式中央主板机箱设计等关键技术,在硬件的高安全、无时延系统切换、节能降耗、优化空间方面有较大的优势,为"双网机"的研究提供了新的思路和方向。

Design and Development of an Integrated Desktop Security Terminal with Internal and External Network Hardware Isolation

The integrated DT860 desktop security terminal with the ability of internal and external network hardware isolation can meet the security need of office network. The terminal uses a self-developed resource connection board with upgraded circuit to make two motherboards interconnection, and adds other hardware resources to build two sets of independent host systems. Compared with traditional computers, the terminal has great advantages in terms of safety, no delay system switching, energy saving and space-optimization because of the applications of key technologies such as secure access through hardware isolation, instantaneous switch, and upright type central motherboard chassis. And it will provide a new direction for studying the future terminals of internal and external network hardware isolation.
