Abstract
The rapid growth in the number of Internet of Things (IoT) devices in critical industries such as healthcare, transportation, and industrial automation has created unparalleled connectivity as well as unique security challenges. These devices are prone to cyber-attacks such as unauthorized access, data interception, and large-scale distributed denial of service (DDoS) attacks. This seminar examines the IoT security protocol landscape with a focus on lightweight, scalable, and context-aware adaptations suited to the myriad operational environments of IoT implementations. Special focus is placed on Artificial Intelligence (AI) techniques, especially anomaly detection and federated learning, as adaptive defense mechanisms, and on blockchain technology as a decentralized trust infrastructure. A blockchainʹs immutability and AIʹs predictive capabilities combine to form a strong data integrity, device authentication, and access control security framework. The seminar outlines critical research gaps and forward-looking proposals by evaluating existing protocols and highlighting cutting-edge blockchain-AI applications in eHealth, smart cities, and vehicular networks.
