Abstract
Post-Quantum Cryptography (PQC) is a rapidly developing field that addresses the potential threat quantum computers pose to the security of current cryptographic algorithms. With the rapid advancement of quantum computing technologies, it has become imperative to identify and standardize new cryptographic techniques that can withstand attacks from quantum computers. This paper explores the motivation behind PQC and provides an overview of the experimental research conducted in the field. It highlights the vulnerabilities of traditional cryptographic algorithms, such as RSA and ECC, to quantum attacks and emphasizes the need for transitioning to quantum-resistant alternatives. The experiments conducted in the PQC domain encompass the evaluation and analysis of candidate algorithms submitted to the NIST PQC competition. These experiments involve comprehensive security assessments, performance evaluations, and code audits to ensure the suitability and effectiveness of the proposed algorithms in real-world scenarios. This paper provides guidelines for organizations and practitioners adopting PQC. It discusses considerations for selecting and implementing post-quantum cryptographic algorithms, including security levels, algorithmic characteristics, performance tradeoffs, and integration challenges. It also outlines the importance of a smooth transition from classical to post-quantum cryptographic systems and highlights the need for standardization efforts to ensure interoperability and compatibility.
