Abstract

This collective body of research explores post-quantum cryptography (PQC), addressing the urgent need to secure digital information against future quantum attacks. It delves into the mathematical foundations and design principles of quantum-resistant schemes, including lattice-based, code-based, and hash-based cryptography. Key topics include NIST’s standardization efforts, the evaluation of candidate algorithms, and significant implementation challenges such as computational overhead and integration into existing systems. Special attention is given to PQC’s impact on Internet of Things (IoT) security and blockchain technology, alongside strategies for optimizing performance and ensuring a smooth transition to quantum-secure digital infrastructures
