Post-Quantum Cryptography

Pranjal, Atul Chaturvedi

TL;DR

Quantum computers threaten classical public-key cryptography by solving hard problems efficiently, jeopardizing RSA and ECC. The paper surveys post-quantum cryptography (PQC) and standardization efforts, detailing algorithm families such as lattice-based, code-based, hash-based, and multivariate cryptography. It highlights the NIST PQC standardization outcome, with CRYSTALS-KYBER for key exchange and CRYSTALS-Dilithium for digital signatures, plus supporting schemes like Falcon and SPHINCS+. The study emphasizes proactive transition strategies, including hybrid approaches and emphasis on quantum-resistant protocols to safeguard digital infrastructure in the quantum era.

Abstract

In this survey we propose to cover the prose of post-quantum cryptography over classical cryptography. We talk about the various cryptographic methods that are being practiced to safeguard our information. The future of secure communication is expected to be the implementation of quantum-safe cryptographic systems, and that in the post-quantum era, the development of post-quantum cryptography is essential for ensuring the security of sensitive data.
