Blockchain Integration with Edge Computing for Securing IoT Networks Through Distributed Ledger Technology

Scalability and automation in “Industrial Internet of Things (IIoT)” aims to improve productivity in smart factory setting. For scalability, protection, collaboration, optimization, and automation in industry, smart systems, Internet of Things (IoT), and information and communication technologies (ICTs) are integrated as an individual organism. This study proposes a safe data-sharing system based on blockchain to provide security in industry with IoT. As per blockchain’s reputation, end-to-end authentication is developed and smart contract can validate security measures of nodes. With categorization and integrity verification in industry and node terminals, the paradigm of blockchain manages dissemination and data collection. The “Proof of Authentication (PoAh)” is a consensus mechanism developed with blockchain network to develop a collaborative network for retaining verification and log data in IIoT. It achieves tracing of endpoint activity and trusted authentication. Blockchain nodes also uses edge computing to provide authentication of devices using PoAh and smart contracts. The proposed architecture achieves high response rate and cuts the time for authentication. The service time in the proposed system shows efficiency of blockchain system for IIoT in comparison to current works. Finally, several block sizes were evaluated for efficient transaction.
