Abstract
Emerging information technologies have accelerated the construction of the Industrial Internet of Things (IIoT). Unfortunately, the explosive growth of various services has caused serious challenges to access control in terms of scalability and trustworthiness. In this paper, we proposed the smart collaborative contract based endogenous access control mechanism. First, access control procedures running on centralized servers are migrated to distributed equipment located inside the data plane, which can reduce the transmission overhead and improve service capacity. Second, the smart collaborative contract is designed for credibility enhancement since part of attackers may attempt to compromise access control. It covers terminal behavior assessment and service request recording. Experiments conducted in a prototype show that the performance of the proposed scheme is better than the traditional solution and is resistant to common attacks.
