Three Layer IoT Architecture: Attacks and Security Mechanisms

Abstract

With the rapid advancement of technology driven by the pervasive influence of the Internet of Things, our world is undergoing a transformative shift. The IoT intricately weaves together diverse objects and devices, forming a complex network that facilitates real-time data exchanges. Projections forecast a substantial increase in global IoT devices, surpassing 29 billion by 2030. This article thoroughly explores the multifaceted landscape of the IoT, focusing on a three-layer architecture enabling connectivity and data exchange among smart objects. Central to this exploration is the acknowledgment of the pivotal role that security plays in IoT systems. The paper delves into potential attack vectors across different layers of the architecture, emphasizing the critical need for robust security measures. It particularly scrutinizes security mechanisms, including encryption standards and lightweight mechanisms, shedding light on their efficacy in mitigating threats. A key takeaway is the identification of security mechanisms that are not only effective but also lightweight in terms of energy consumption. Additionally, the paper extends its analysis to a practical use case involving drones, offering valuable insights into the application of discussed principles in real world scenarios. Navigating the constantly evolving IoT realm requires a profound understanding of these intricacies to ensure security robustness and fully harness the potential of interconnected technologies. The conclusion outlines future prospects and underscores indispensable considerations in the ever-evolving landscape of the Internet of Things, with a noteworthy achievement in gaining insights into diverse attack scenarios and discovering security mechanisms that are both effective and energy-efficient.
