物理隔离环境下数据安全转发的技术构思

The Technological Conception of Data Transmitting Safely under Physical Isolation

物理隔离的封闭性是为防止外来闯入和信息外泄 ,数据转发的开放性则是沟通与外界联系。针对封闭性和开放性这一对矛盾 ,拟提出一种基于物理隔离的数据安全转发的技术构思。这个构思是欲维持内外网在传导、辐射和存储上的物理隔断 ,利用定向采集、中间缓冲、数据扫描等技术 ,使内外网络在不连通的情况下实现动态、准实时的数据安全转发。详细地讨论了物理隔离条件下数据转发的技术途径和实现方法 ,并针对可能出现的安全隐患进行了安全分析 ,探讨了安全策略 。

Physical Isolation obturate is to prevent computers from being attacked from the outside and giving the information away. Data transmitting openness is linked up with the outside world. Regarding the contradiction between the obturate and openness. This paper puts forward a kind of technological conception about data transmitting safely based on the physics isolation. The conception is to maintain the internal and external network in conductivity and radiation and physics cut off so as to transmit data in the condition of the internal and external network in disconnection, using directional collection, intermediate buffer and data scanning. In this paper, the technological channels and the methods of data transmitting have been discussed in detail in the condition of physical isolation. According to the hidden trouble, This paper also discussed the safe strategy and made some safe measures.
