I NTRODUCTION The Internet of Things (IoT) landscape has witnessed ex- ponential growth in recent years, with billions of intercon- nected devices spanning various domains such as healthcare, transportation, agriculture, and smart cities. This interconnect- edness has facilitated unprecedented levels of data collection, analysis, and automation, leading to significant advancements in efficiency, productivity, and quality of life. However, along- side these benefits, the proliferation of IoT devices has also introduced profound security challenges [1]–[4]. Security has emerged as a paramount concern in IoT ecosys- tems due to the sensitive nature of the data transmitted and pro- cessed by connected devices. With IoT devices collecting and exchanging vast amounts of data, ensuring the confidentiality, integrity, and availability of this data has become critical. Moreover, the interconnected nature of IoT networks amplifies the potential impact of security breaches, posing risks to personal privacy, financial assets, critical infrastructure, and even public safety [2], [4]. A. Motivation The growing importance of security in IoT ecosystems necessitates robust measures to safeguard against evolving cyber threats. Cryptoprocessors, specialized hardware com- ponents dedicated to cryptographic operations, offer a com- pelling solution to enhance the security posture of IoT devices [5], [6]. By offloading cryptographic tasks from general- purpose processors to dedicated hardware, cryptoprocessors can mitigate various security vulnerabilities and improve the efficiency of cryptographic operations in resource-constrained IoT environments. Cryptoprocessors play a pivotal role in addressing the unique challenges faced by IoT devices, including limited computational resources, constrained power budgets, and sus- ceptibility to physical attacks. With cryptographic algorithms becoming increasingly complex and resource-intensive, the integration of cryptoprocessors enables IoT devices to per- form cryptographic operations efficiently while minimizing energy consumption and latency. Furthermore, cryptoproces- sors provide hardware-based protection against a wide range of attacks, including side-channel attacks, fault injections, and quantum attacks, thereby enhancing the overall security resilience of IoT ecosystems [7]–[9]. B. Objective The objective of this paper is to explore the integration of cryptoprocessors for enhanced security in IoT environments. By analyzing recent advancements in hardware support, cryp- tographic processors, and energy-efficient designs, this study aims to provide insights into the role of cryptoprocessors in fortifying the security posture of IoT ecosystems. Specifically, the objectives of this paper include: • Reviewing state-of-the-art research papers on cryptopro- cessors and their applications in IoT security. • Examining the key features and capabilities of cryptopro- cessors, including hardware architectures, cryptographic algorithms, and energy efficiency. • Identifying emerging trends and challenges in the inte- gration of cryptoprocessors for IoT security. 524 2024 20th International Conference on Distributed Computing in Smart Systems and the Internet of Things (DCOSS-IoT) 2325-2944/24/$31.00 ©2024 IEEE DOI 10.1109/DCOSS-IoT61029.2024.00083 2024 20th International Conference on Distributed Computing in Smart Systems and the Internet of Things (DCOSS-IoT) | 979-8-3503-6944-1/24/$31.00 ©2024 IEEE | DOI: 10.1109/DCOSS-IoT61029.2024.00083 Authorized licensed use limited to: Cyprus University of Technology.
