IoT Devices Authentication using Blockchain Technology

Abstract

The Internet of Things (IoT) has brought revolution the way we live and work, but with this revolution it has also brought new security challenges. IoT devices often lack strong authentication mechanisms, making them vulnerable to cyber- attacks or malicious intents. Blockchain technology has come up as a prospective solution to this problem, offering a secure and decentralized way to authenticate IoT devices. In this paper, we propose a novel approach to IoT authentication using blockchain technology. Our approach leverages the decentralized properties of blockchain technology to provide secure and reliable authentication for IoT devices. We dis- cuss the challenges of implementing blockchain-based IoT authentication, such as scalability and privacy, and propose solutions to address these challenges. we tend to propose a blockchain primarily based authentication theme named Bubbles of Trust. wherever solely devices settled within a selected bubble will be sure and attested with. We also present a proof-of-concept implementation of our approach authenti- cation process, demonstrating how blockchain-based authentication can be used to securely authorize and validate transactions between IoT devices. Our implemen- tation uses a combination of cryptographic techniques, such as digital signatures and public-key cryptography, to ensure the integrity and authenticity of transac- tions. Overall, our approach offers a promising solution to the security challenges of IoT devices in matters of security. It provides a secure and decentralized authen- tication mechanism that can help prevent unauthorized access or communication and protect sensitive data
