基于知识隐藏的星载计算机系统安全研究

On-board Computer Security Research Based on Knowledge Hiding

在现代战争中 ,卫星的信息安全与可靠性直接关系交战方能否具有一定的信息优势 ,能否掌握战场的主动权。星载计算机系统、通信系统的安全与可靠性是关键。分布式、多总线、多处理单元的冗余设计、看门狗技术是目前用来保证星载计算机系统可靠性的主要手段。文章从知识隐藏的角度 ,提出用弹性计算理论来保证星载计算机系统容错、容入侵的思路和方法。论文给出了知识隐藏的概念 ,分析了 3种知识隐藏方法 ,围绕弹性计算模型 ,提出了基于弹性计算模型的星载计算机系统的文件系统。

In modern warfare, information security and reliability of Satellites directly relate to information advantage and active might of the two belligerent parties.Security and reliability of on-board computer system and communicating system is critical. The redundancy design of distributed systen、multi-bus、multi-process-unit, watch-dog technology currently are the main mesns to ensure reliability of on-board computer system. This article uses resilient compute theory to insure fault-tolerance and intrusion tolerance ability of on-board computer from knowledge hidng. This article gives the concept of knowledge hiding and analyses thtee kinds of knowledge hiding techniques, surrounding resilient computer model, construct file system of on-board computer system based on resilient computer model,and this file system is rinished mostly.
