Abstract
With the increasing proliferation of Internet of Things (IoT) devices, security and integrity of firmware updates are critical concerns. IoT devices are often deployed in sensitive environments, and any compromise in their firmware can lead to serious security risks, including unauthorized control and data breaches. This paper investigates the potential of leveraging blockchain technology to enhance the security of firmware update delivery. By utilizing blockchain-based verification protocols, we propose a secure and decentralized approach for ensuring the authenticity of firmware updates. The proposed solution offers transparency, immutability, and traceability, addressing the challenges posed by traditional centralized update mechanisms. This paper presents a detailed review of existing literature on IoT security, blockchain applications, and secure firmware update methods, followed by an analysis of the proposed blockchain-based verification protocol.
