Access control model based on weighted interval-valued fuzzy reasoning
基于区间值加权模糊推理的访问控制模型

Pervasive computing has been recognized as the future of mainstream computing model in the whole academic and industry, its security issue is the foundation of information security issues. However, the traditional access control models take a system-centric view of protecting resources, and they don't take the context into account when controlling the permissions. In order to meet the need of dynamic access control policies and fuzzy uncertain context of pervasive computing, this paper introduced an access control model, which based on the theory of fuzzy set and the method of weighted interval-valued fuzzy reasoning. Besides that, it applied weighted fuzzy matching function and interval-valued weighted fuzzy reasoning method to realize the consistency between the access control policy and the actual need of security.
