Blockchain Enabled Optimal Lightweight Cryptography Based Image Encryption Technique for IIoT

Industrial Internet of Things (IIoT) and Industry 4.0/5.0 offer several interconnections between machinery, equipment, processes, personnel in diverse application areas namely logistics, supply chain, manufacturing, transportation, healthcare. The conventional security-based solutions IIoT environment get degraded due to the third parties. Therefore, recent blockchain technology (BCT) can be employed resolve trust issues eliminate need for this paper presents a novel enabled secure optimal lightweight cryptography based image encryption (BC-LWCIE) technique industry 4.0 environment. In addition, BC-LWCIE involves design an LWC hash function with key generation using chicken swarm optimization (CSO) algorithm. Moreover, CSO algorithm derives fitness maximization peak signal noise ratio (PSNR). stores cryptographic pixel values encrypted BCT ensure secrecy order highlight enhanced security performance technique, series simulations were carried out results demonstrated betterment over techniques.
