Fortifying IoT Ecosystems: A Hybrid Security Framework with Blockchain & Artificial Intelligence

Abstract

The rapid expansion of the Internet of Things (IoT) requires security solutions that address vulnerabilities while operating within resource-constrained environments. Our solution introduces a hybrid framework that combines Blockchain for decentralized, tamper-resistant communication with Artificial Intelligence (AI) for real-time anomaly detection. A local IoT testbed has been implemented using an RFID sensor, blockchain nodes, and edge AI modules to continuously monitor system behavior. This system has been evaluated for latency, throughput, power consumption, and detection accuracy. Results demonstrate that combining blockchain’s immutability with AI’s adaptability enhances IoT security and reliability in practical deployments.
