Research on Network Access Control in the Open Internet of Things Environment

With the continuous deepening of social informatization, the Internet of Things (IoT) devices are used in large quantities. Traditional centralized access control cannot meet the network access control requirements of large-scale IoT environments. Access control is one of the importation technology of information security. This paper establishes the dynamic game access control model which encourages interactive entities to rationally choose strategies expected by the system driven by its own benefits through the designed mechanism. Taking benefits as the driven force, the mechanism rewards the honest nodes and punishes and restrains the non-honest nodes, and then reaches the general state of equalization between entities which meets the goal. Finally, experiments prove that this method is effective in the open Internet of Things, which can greatly enhance the security of data access between IoT sensors, and can effectively protect the privacy of network entity data.
