On the design and implementation of a secure blockchain-based hybrid framework for Industrial Internet-of-Things

Industrial Internet-of-Things (IIoT) refers to the next stage in the evolution of organizations where collecting, analyzing, recording the data and controlling the entire activities of the various entities is achieved with connected machines in real time with enhanced quality and minimum production cost. Although, various phenomenal schemes for cross management activities exist in current systems, however there are still several concerns with such setups within the organizations. Further, the introduction of Internet-of-things (IoT) within the industries is increasing the scope of applications by connecting every device with the Internet. However, these IoT devices are prone to various attacks by the intruder, thus affecting the industry with lower production and high manufacturing cost, to name a few. To address these issues, Blockchain is considered as one of the best scheme which offers protection and secrecy of control systems in real time up to certain level. In this paper, we have proposed a hybrid Blockchain mechanism for providing security for a multi-national level IIoT with offices located in multiple countries. The proposed framework is validated rigorously against various security metrics over conventional mechanism. The simulation results suggest that our proposed solution leads to 94% efficiency in terms of DoS and DDoS threat, message alteration attack and authentication delay.
