【摘要】 在信任模型基础上,提出一种基于信任度的模糊自适应访问控制模型。该模型扩展信任度的概念,建立权限的区间值模糊策略规则,通过对与主体相关的上下文信息的模糊推理实现授权的有效控制。描述模型的构成要素,研究模型的区间值模糊推理算法,为解决普适计算环境下动态访问控制授权问题提供了一定的技术手段。更多还原

【Abstract】 Based on the current trust models,proposed the trustworthiness-based fuzzy adaptive access control model for pervasive computing(TBFAAC).The model extends the concept of trustworthiness,establishing the interval value fuzzy policy rules of permissions,achieving the effective authorization through the fuzzy reasoning based on the context information related to the subject.Described the main elements and the interval value fuzzy reasoning algorithm of the model.The TBFAAC model provides the technology for dynamic authorization in pervasive computing.更多还原
