A Design and Implementation of Access Control Mechanism based on the Integrated Information Model

This paper presents a design of an access control mechanism that can resolves the complicated problems of access control requirements in modern information communication applications. In this paper, we proposed an integrated information model which can satisfy the combined goals of confidentiality, integrity and availability of any resource. We defined an integrated information model from the view points of identity-based, rule-based and role-based policy and implemented six access control operations. The proposed integrated information model can protect to unauthorized access to any resource based on the multilevel security policies of security label, integrity level, role and ownership.
