Analysis of Post Quantum Cryptography Algorithms concerning their applicability to IoT devices

Abstract

The increasing ubiquity of Internet of Things (IoT) devices has necessitated robust security measures, especially with the impending threat of quantum computing to conventional cryptographic protocols. In this study, we address the imperative of selecting an optimized post-quantum cryptographic algorithm tailored for implementation on resource-constrained IoT devices while ensuring compliance with stringent security standards. This research employs a comprehensive evaluation framework that considers the unique constraints of IoT devices, including limited computational capabilities and memory resources. Furthermore, our assessment accounts for the diverse security requirements stipulated by prevailing standards to guarantee resilience against both classical and quantum threats. Through a systematic analysis of various post-quantum cryptographic algorithms, encompassing factors such as computational efficiency and resistance to quantum attacks, this study identifies a select set of algorithms that exhibit promising suitability for IoT device deployment. The evaluation considers renowned standards, including NIST’s Post-Quantum  Cryptography Standardization initiative to align with industry best practices and interoperability. The findings pre- sented in this study offer guidance to IoT device manufacturers, system architects, and security practitioners in making informed decisions regarding the adoption of post-quantum cryptographic algorithms. The selected algorithms not only demonstrate adeptness in mitigating quantum threats but also address resource constraints inherent in IoT environments, ensuring a secure foundation for the rapidly expanding ecosystem of interconnected devices.
