Blockchain-Based IoT Security Framework for Critical Infrastructures

Abstract

This paper presents a comprehensive Blockchain-Based IoT Security Framework tailored for critical infrastructures. As IoT devices proliferate, they expose vulnerabilities that can jeopardize essential services. Our framework leverages blockchain technology to enhance data integrity, authentication, and access control across interconnected IoT networks. By integrating smart contracts, the framework automates security protocols, ensuring real-time responses to potential threats. We analyze key components, including decentralized identity management, consensus mechanisms, and cryptographic techniques, to establish a robust security posture. This innovative approach not only fortifies the resilience of critical infrastructures but also promotes trust among stakeholders.
