In the rapidly evolving landscape of industrial ecosystems, Industrial IoT networks face increasing security challenges. Traditional security methods often struggle to protect these networks adequately, posing risks to data integrity, confidentiality, and access control. Our research introduces a methodology that leverages blockchain technology to enhance the security and trustworthiness of IoT networks. This approach starts with sensor nodes collecting and compressing data, followed by encryption using the ChaCha20-Poly1305 algorithm and transmission to local aggregators. A crucial element of our system is the private blockchain gateway, which processes and classifies data based on confidentiality levels, determining their storage in cloud servers or the Interplanetary File System for enhanced security. The system’s integrity and authenticity are further reinforced through the proof of authority consensus mechanism. This system employs Zero Knowledge Proof challenges for device authorization, optimizing data retrieval while maintaining a delicate balance between security and accessibility. Our methodology contributes to mitigating vulnerabilities in Industrial IoT networks and is part of a broader effort to advance the security and operational efficiency of these systems. It reflects an understanding of the diverse and evolving challenges in IoT security, emphasizing the need for continuous innovation and adaptation in this dynamic field.

Today, the primary issues for both physical and online retailers are fake and stolen goods. The likelihood that this product is fake is unknown to consumers. They lack a clear method to check the product’s integrity. This not only jeopardizes consumer trust but also imposes significant financial ramifications on both buyers and sellers. Therefore, we suggest a method in which we incorporate blockchain technology to confirm the product’s integrity. Central to our proposition is the integration of Non-Fungible Tokens (NFTs) as unique digital identifiers, combined with the dual security layers of holographic labels and RFID tags. This system operates on a private blockchain, ensuring enhanced scalability and transaction efficiency. Furthermore, the mechanism incorporates a collateral system initiated upon order placement, incentivizing honesty and timely delivery among participants. In the event of discrepancies, a robust dispute resolution system, underpinned by a voting mechanism, ensures fairness and trustworthiness. Our experimental implementation demonstrates the system’s effectiveness in reducing costs and enhancing transparency in supply chain management. The results highlight the potential of blockchain technology in revolutionizing supply chain management, offering a compelling alternative to traditional systems with reduced costs and increased security and transparency.
