Quantum Safe cryptography – An Overview
S. Pandikumar, Pallavi M O, C Dhanush, m Arun · 2024
Quantum-safe cryptography is the term that specifies cryptographic methods secured against the threats of quantum computing. Among them are Quantum Key Distribution, which provides information-theoretic security, and Post-Quantum Cryptography, which provides scalable authentication in high-density networks but lacks the same level of theoretical security as the former. In this context, a hybrid cryptosystem that integrally combines QKD and PQC should be created to build a robust quantum-safe system. Moreover, in blockchain technology and machine learning models, quantum algorithms play an important role by improving encryption and key generation. Quantum-safe cryptography represents an important step toward the future-proofing of digital communications and systems
