Network Resilience and Secure Confidentiality in Industrial-IoT through Software-Defined Networking

The ever-expanding Industrial Internet of Things (IIoT) demands highly resilient and secure network architectures. While the execution of Software-Defined Networking (SDN) tackles the issue of heterogeneity in IIoT networks by the provision of centralized control and programmability, its scalability is exacerbated in large-scale IIoT deployments. This paper highlights the vitality of a distributed control plane architecture for SDN to overcome the scalability issues, thereby bolstering its efficiency. Furthermore, we propose a (t, n) threshold paradigm which ascertains that only authorized entities can access private data. The proposed protocol promotes reliability and data privacy, paving the way for secure operation within convoluted IIoT networks.
