摘要：Recently, attribute based access control (ABAC) has received considerable attention from thesecuritycommunity for its policy flexibility and dynamic decisionmaking capabilities. The generalidea of ABAC is todetermine the authorization decisions of an access request based on variousattributes of the entities involved in theaccess (e.g., users, subjects, objects, context, etc.). Hence,in an ABAC system, proper assignment of attribute values todifferent entities is necessary toprotect against unauthorized access. There has been considerable prior research forABAC invarious aspects such as formal models, enforcement models, policy composition languages and soon.However, mechanisms for ensuring proper attribute value assignments to entities have not beenwell studied.
