Abstract: This paper explores the potential of blockchain technology in addressing the security challenges of the Internet of Things (IoT). The IoT ecosystem faces issues such as authentication, data integrity, secure communication, supply chain security, and auditing. Blockchain, with its decentralized and tamper-resistant nature, offers solutions to these challenges. The paper discusses the key concepts of blockchain, its types, consensus mechanisms, and the security challenges in IoT. It then highlights how blockchain addresses these challenges through decentralized ledgers, data immutability, identity management, secure communication, smart contracts, decentralized consensus, supply chain security, and auditing benefits. Case studies illustrate blockchain-based solutions, and implementation considerations and future directions are explored. Ultimately, blockchain technology has the potential to revolutionize IoT security by ensuring trust, privacy, and integrity in IoT systems and data.
Keywords: Blockchain technology, Internet of Things (IoT), security challenges, authentication, data integrity, secure communication, supply chain security, auditing, decentralized ledger, tamper resistance, identity management, smart contracts, decentralized consensus, case studies, implementation considerations, future directions.
