Trust and Attribute-based Dynamic Access Control Model For Internet of Things

The Internet of Things(IoT) is a burgeoning network technology which realizes the information communication from human beings to objects and even objects to objects. Different types of connected smart objects distributed in the IoT system dynamically and data access between each other randomly that put forward stricter requirements to access control technology. ABAC is deemed to be a suitable access control model in distributed environment, but security in the Internet of things needs to be paid more attention. In this paper, we design a trust attribute-based access control model that introduces trust evaluation module and accomplishes authorization with synthetic constraint which integrates dynamic trust attribute and static multiattribute. Finally, our model has more superior characteristics and improves the security of IoT system through experiment results.
