| 摘 要： | 分析了策略系统存储模型在判断策略问条件变量值的相交性方面存在的不足,研究了概念格结构在该方面的优势,提出了基于分类概念格的动态策略存取模型,利用策略属性值之间的偏序关系,将动态策略仓库组织为概念格.设计了基于概念格的策略冲突检测算法,用超概念一子概念查找操作代替属性值相交性判断,缩减了冲突检测空间,提高了冲突检测效率.分析了算法的性能,通过仿真验证了算法的有效性.

| Abstract: | A new access model for dynamic polices was proposed after disadvantages of other access models and advantages of concept lattice in getting the intersection set of attribute values for two policies was analyzed.The new access model was based on classification concept lattice.Dynamic policies were organized into a concept lattice according to the partial order relation among their attribute values.A novel conflict detection algorithm was proposed based on concept lattice to greatly increase efficiency of con... |
