Decentralized Trust Mechanisms in Blockchain Redefining Security Protocols for IoT Networks
J Santhosh, P. Arulkumar · 2024
The rapid expansion of the Internet of Things (IoT) necessitates robust, scalable, and secure frameworks for managing interactions among vast networks of devices. Traditional centralized trust models have become insufficient in addressing security, data integrity, and scalability issues. Decentralized trust mechanisms, powered by blockchain technology, offer a promising alternative by enabling trustless, autonomous interactions and eliminating single points of failure. This chapter examines how blockchain-based decentralized trust mechanisms are reshaping IoT security protocols, focusing on the integration of consensus algorithms for efficient, real-time data validation. It explores the importance of autonomous validation, the transition from centralized to decentralized models, and the creation of self-managed IoT ecosystems. The chapter also discusses the factors influencing the choice of consensus algorithms tailored to IoT security needs. Ultimately, decentralized trust mechanisms offer a path towards more secure, scalable, and resilient IoT networks, with significant implications for industries like smart cities, healthcare, and autonomous systems.
