基于模糊的强制访问控制模型实现机制研究

Research for Mechanism of Mandatory Access Control Model Based on Fuzzy

强制访问控制主要用于多层次安全级别的军事系统中,因实体的安全级别很难确定,故存在实现工作量较大、管理不便和不够灵活的缺陷.在假设范畴相同的条件下,多次运用模糊聚类方法,按越权带来的经济损失额、越权率两个统计指标将实体分为重要、一般、不重要三类,并分别赋予权值,给出了确定实体安全标签的算法以及计算公式.

Mandatory access control mainly applys in military system with multilevel Safe rank, which exists some limitations resting with realizing complexity, management inconveniently and unskillfully, because of defining hardly subjects and objects＇ security level. Under the hypotheses of same category, fuzzy clustering method is applied to the classification of entities with the important, the general, the unimportant, which endow with different weight, then algorithm and calculating formula are given in the paper, which can ascertain entities＇ security level.
