Abstract: It is stated in GB17859-1999 that the fourth level security information system must implement structured protection function,to which the availability way is dividing the system into different layers.Based on the ideology of Trusted Computing,by modeling the root of trust as the minimal element of a partial order set and using related knowledge about the complete partial order in set theory,a method for layering components of a system is proposed via dependencies between them,followed by the proof of the completeness of the method.Further discussion also shows that the method can be employed in many other aspects of strengthening the system’s security.

Key words: structured protection, layering method, trusted computing, complete partial order, dependency

摘要: GB17859-1999中要求四级以上安全操作系统必须实现结构化保护功能,而层次化方法是实现结构化保护的一个有效途径。基于可信计算思想,将可信根抽象为偏序集中的最小元,利用集合论中完全偏序集的相关知识,通过组件间的依赖关系,提出了一种组件层次划分方法,并证明了层次划分方法的完备性。进一步分析表明,该方法能有效应用于增强系统安全性的研究。
