Comprehensive Taxonomy and Advancements in IoT Device Authentication Schemes

The rapid proliferation of Internet of Things (IoT) devices has underscored the critical importance of robust authentication frameworks to ensure the security and integrity of these interconnected systems. This paper presents a comprehensive exploration of IoT device authentication mechanisms, addressing the multifaceted challenges posed by the diverse nature of IoT devices and their resource constraints. Through an in-depth review of the existing literature, this study categorizes and analyzes various authentication approaches, ranging from traditional methods like pre-shared secrets, PUF, RFID and to novel lightweight protocols tailored to the limitations of resource-constrained devices. Furthermore, this research delves into the evolving landscape of IoT security, considering advancements such as the integration of blockchain technology and edge computing for enhancing authentication processes. By synthesizing insights from a multitude of scholarly works into a taxonomy, this paper not only offers a holistic understanding of the current state of IoT device authentication but also identifies gaps and challenges that warrant further investigation.
