Integrated Framework for Industrial Internet of Things Authentication Leveraging Block chain, Proxy Re-encryption, and AI Techniques

The digital evolution has fostered the rise of the Internet of Things (IoT) and its industrial counterpart, the Industrial Internet of Things (IIoT). While IoT is used to connect everyday devices for daily use, IIoT is responsible on optimizing the industrial processes. This paper first explores blockchain-enhanced authentication mechanisms in industrial settings, highlighting their benefits, challenges, and practical applications. In response to the challenges faced, we propose a novel framework that integrates and enhances upon the leading solutions. Our proposed solution is integrated with block chain and RFID technologies, proxy re-encryption, and a block chain authentication mechanism empowered with Transfer Learning (TL). This integrated approach aims to enhance security, efficiency, and adaptability in IIoT environments. Through comprehensive analysis, the paper aims to provide in-depth review into the potential applications and future directions of blockchain-enabled authentication methods in IIoT, contributing to the advancement of secure and efficient industrial operations.
