Research on the Application of Access Control Based on Fuzzy Constraints

With the rapid development of information systems, the security is a fundamental issue of information security. The traditional access control model manages from the perspective of the system as a whole and lacks consideration of contextual information, dynamism and flexibility. The combination of applied fuzzy constraints and access control can well satisfy the dynamic adaptiveness of access control policies and the fuzzy uncertainty of contextual information. In this paper, we summarize the current status of fuzzy constraint-based access control from the application scenarios of cloud computing and risk-based systems. Facing the challenges of the current fuzzy constraint-based access control mechanism, future research directions are proposed.
