Blockchain Based Authentication System for Internet of Things

Abstract: The rapid expansion of the Internet of Things (IoT) introduces complex security challenges, particularly in the areas of device authentication, data integrity, and decentralized management. Traditional security mechanisms often fall short in addressing these issues due to the unique constraints and scalability requirements of IoT networks. In response, this paper proposes a secure, blockchain-based framework for IoT device registration and authentication, implemented in MATLAB. Utilizing the principles of Elliptic Curve Cryptography (ECC) for cryptographic key generation, our framework ensures a high level of security that is both efficient and scalable, suitable for the diverse ecosystem of IoT devices. Through the integration of blockchain technology, we offer a decentralized approach to IoT security, enhancing data integrity and device authenticity across the network. The proposed MATLAB simulation provides a practical and accessible platform for exploring the application of blockchain in securing IoT devices, demonstrating the framework's effectiveness in real-world scenarios. This work not only addresses the immediate security concerns of IoT networks but also lays the groundwork for future research and development in the convergence of blockchain technology and IoT security solutions.
