Blockchain technology, renowned for its ability to securely store data, hashes, and signatures permanently, faces unprecedented challenges in secure Consumer IoT (CIoT) networks with the advent of quantum computing. This paper proposes a set of robust quantum-based protocols and techniques to address these challenges by enhancing the security, scalability, and reliability of CIoT systems in the face of quantum threats. Updating the blockchain infrastructure is imperative to ensure ongoing security, which involves forks or protocol adjustments to establish new post-quantum chains and addresses, requiring rapid data and asset migration by users. Blockchain guarantees data integrity through an immutable ledger of transactions distributed via cryptographic hashes. The proposed quantum protocols and techniques enhance scalability and reliability and address the unique security needs of both commercial and governmental applications in secure CIoT networks through immersive embedded cyber-physical systems. These include Quantum Currency Security Protocols, Distributed Ledger Data Blocks, Quantum Ledger Verification, Quantum Solutions for Middleman Attacks, and the integration of Elliptic Curve Cryptography (ECC)-based security measures. By integrating these methods, the proposed approach ensures robust protection against emerging quantum threats, thereby securing sensitive information and transactions. |
