Trustworthiness-based fuzzy adaptive access control model for pervasive computing
普适计算环境下基于信任度的模糊自适应访问控制模型*

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.
