基于可信度的多级网络访问控制机制
Access control mechanism of multi-level network based trust evaluation
摘要
Abstract
This paper analyzes problem of BLP model which is applied to multi-level network, and puts forward access control of multi-level network based on trust evaluation.The method collects evidences of access history of subject from audit systems in the same secure domain,then evaluates trust degree of subject about violating confidentiality rule by evidences, and adjusts secure label of subject and being of object,which can not only increase flexibility and availability but also reduce risk of information system by misuse of credible subject's authority in BLP model.关键词
