摘要 多级安全数据模型的研究重点主要集中在模型的安全性和表达能力上,对数据模型的效率关注不够。尝试从一个新的角度——数据紧凑度对数据模型进行分析和比较,对于多级安全数据模型的改进和实现具有一定的指导意义。 At present the researches of Multilevel Secure Data Model are focused on security and expression of model,while the efficiency of model is not given enough concern.In this paper,we attempt from a new view--Data Compact Ratio,to analyze and compare the data model,which is instructive for the improvement and realization of Multilevel Secure Data Model.
