Chapter 1: Introduction
1.1 Background
The Internet of Things (IoT) has emerged as one of the most transformative paradigms in modern computing, enabling billions of devices to communicate, share data, and automate processes across diverse domains such as healthcare, transportation, manufacturing, and smart homes. These devices range from simple sensors to complex embedded systems, all interconnected through communication protocols like MQTT, CoAP, and HTTP.
While IoT promises efficiency and innovation, it also introduces unprecedented security challenges. The distributed nature of IoT networks, coupled with resource-constrained devices, makes them highly vulnerable to cyberattacks such as data interception, spoofing, denial-of-service (DoS), and unauthorized access. Traditional cryptographic methods, though effective in conventional computing environments, often fail to provide lightweight, scalable, and adaptive protection for IoT ecosystems.
Machine Learning (ML), a subset of Artificial Intelligence (AI), offers a promising solution by enabling systems to learn patterns, detect anomalies, and adapt to evolving threats in real time. By integrating ML into secure communication frameworks, IoT devices can achieve enhanced confidentiality, integrity, and availability of data while maintaining efficiency.
1.2 Problem Statement
