A SDN-based IoT Fine-grained Access Control method
â??With the rapid growth of the number of IoT (Internet of things) devices, the flexible and high-speed configuration of the IoT has become a major requirement. SDN (Software Defined Network) technology has been introduced into the IoT to achieve network control and forwarding separation. Security issues are the key to IoT applications. Among the security issues of IoT, access control is one of the most important. How to solve the access control problem under the SDN architecture faces new challenges. This paper designs a fine-grained access control method for IoT devices based on SDN, and a test platform is built to verify the method. The results show that the access control method can effectively filter the illegal access of different device sources, request actions, access time and other elements.
