细粒度基于传递功能的约束委托模型
Fine-Grained Constrained Delegation Model Based on Transferable Capability
摘要
Abstract
In order to ensure system security and reflect flexibility in delegations , a fine-grained constrained dele-gation model was proposed by introducing the transferable capability which was independent of the role concept and could transfer all or part of delegators ’ permissions.The model can support the fine-grained, constrained and multi-step delegations.Two methods of construction and reduction were adopted to verify the consistency of delegation con -straints.Theoretical analyses and delegation examples showed that the model is secure and flexible .关键词
