IoT Device Authentication and Verification Through Blockchain Methods and Challenges

Abstract

The exponential growth of Internet of Things (IoT) devices has heightened concerns regarding security and data integrity, prompting the need for robust authentication and verification mechanisms. Blockchain technology, with its decentralized nature and cryptographic security, emerges as a promising solution to these challenges. This paper explores the applicability of blockchain methods for IoT device authentication and verification, highlighting the architectural integration, cryptographic protocols, and consensus algorithms suited for IoT environments. The study also addresses the significant challenges such as scalability, latency, and energy consumption that impede the adoption of blockchain in IoT. By analyzing existing blockchain solutions and their effectiveness in IoT contexts, this paper provides insights into the potential of blockchain to enhance the security posture of IoT networks without compromising operational efficiency.
