A Secure Dynamic Authorization Model Based on Improved CapBAC

The emergence of new concepts of Internet of Things and Resource Sharing has brought great convenience to modern life, at the same time, it also brings much more privacy and security issues. The authorization of IoT equipment is one of the most difficult and hot issues. In this paper, we propose a secure dynamic authorization model and realize 1) flexible authorization by designing a time-sharing authorization algorithm based on time slice and 2) safe and dynamic authorization by introducing JWT authentication technology to CapBAC model. Experiments on real intelligent parking platform show that the proposed model in this paper can bring up to 50% growth in average utilization of the parking system.
