基于開(kāi)放邏輯R反駁計(jì)算的訪問(wèn)控制策略精化
[Abstract]:Policy refinement is an important method to solve the complexity of configuration of access control policies in distributed applications. The existing refinement techniques give the methods of policy hierarchy description and layer by layer refinement, but the ability to deal with the problem of policy correlation is insufficient. Based on the refined tree description strategy and policy association, based on the decision of leaf node policy conflict, the open logic R is used to refute and analyze the attribute of refined tree policy association, which can resolve the policy conflict and ensure the policy mutex, combination and access path cooperation. The refined mapping is correct, and it can resolve the conflict of different types of strategy in order and choose the conflict freely. The experimental and computational results show that the method meets the needs of SAA S platform customer application system strategy refinement.
