【摘要】:策略精化是解決分布式應(yīng)用訪問控制策略配置復(fù)雜性的重要方法,現(xiàn)有精化技術(shù)給出了策略分層描述和逐層精化的方法,但處理策略之間關(guān)聯(lián)問題的能力不足.基于精化樹描述策略和策略關(guān)聯(lián),基于葉結(jié)點(diǎn)策略沖突判斷,采用開放邏輯R反駁計(jì)算分析精化樹策略關(guān)聯(lián)屬性,能夠消解策略沖突同時保證策略互斥、組合、訪問路徑協(xié)同、精化映射等關(guān)聯(lián)正確,并能夠按序消解不同類型策略沖突、自由取舍相沖突的策略.實(shí)驗(yàn)與分析計(jì)算性能表明,該方法符合Saa S平臺客戶應(yīng)用系統(tǒng)策略精化需求.
[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.
