A New Blockchain Based Model for Protecting IoT Devices from Spoofing Attack

Abstract

The Internet of Things (IoT) has become a cornerstone of modern technology in the age of rapid digitalization, connecting billions of resource-constrained wireless devices. While this connectivity enables numerous innovations, it also introduces serious security challenges, particularly spoofing attacks that exploit the limited processing capabilities of IoT devices. This study proposes a novel blockchain-based model to enhance IoT network security, with a specific focus on detecting and mitigating spoofing threats. The model demonstrates strong defense capabilities by integrating the Ethereum blockchain and smart contracts into an IoT simulation environment using Raspberry Pi and Raspbian OS. The experimental setup involved simulating spoofing scenarios and measuring system performance using detection accuracy and processing time metrics. The results showed that the proposed model successfully prevented nearly 80% of spoofing attempts. However, blockchain integration led to a 42% increase in processing time, signaling the need for future optimization. Despite this trade-off, the proposed model offers a practical and scalable solution for securing IoT systems. This research contributes to the advancement of decentralized IoT security and sets the groundwork for future studies focusing on reducing computational overhead and expanding applicability across diverse IoT environments.
