Abstract
Industrial Internet of Things (IIoT) is a communication environment that consists of various interconnected sensing devices, instruments, and other devices connected together with industrial software tools and applications. The important applications of IIoT include industrial automation, predictive maintenance, smart logistics management, power management, smart package management and smart robotics. However, IIoT may be vulnerable to different types of attacks as the IoT smart devices communicate among each other via insecure communication means. Thus, there is an essential requirement of deployment of secure access control scheme in IIoT environment, which is one of the important security services for securing IIoT. In this paper, we propose a novel access control scheme for fog based IIoT communication, called SAC-FIIoT. We provide the details of network model as well as threat model, which are required to design SAC-FIIoT. The security analysis of SAC-FIIoT shows its resilience against various types of possible attacks. SAC-FIIoT is also compared with other related competing existing schemes and it was found that its performance is better than these competing schemes. Therefore, SAC-FIIoT is suitable for access control in a fog-based IIoT environment.
