Jayasudha Yedalla

Abstract: The paper proposes strategic steps that organizations can take to future-proof their security architecture against quantum threats for the security of data integrity and confidentiality in the post-quantum era. it is a very threat that quantum computing is advancing too fast, and the classical cryptographic systems will be in danger. Therefore, we need to modify the methods of cryptography in Quantum-Safe Cryptography. In this paper, we focus on exposing the vulnerabilities of existing public-key cryptosystems faced with quantum attacks and the direction of the post-quantum cryptographic (PQC) algorithm in securing the underlain infrastructure. The paper discusses ongoing efforts to standardize cryptosystems led by the National Institute of Standards and Technology (NIST). It overviews several quantum-resistant cryptographic techniques: lattice-based, hash-based, and code-based examples. Moreover, the paper also outlines difficulties in implementing quantum-safe cryptography solutions into currently in-place cybersecurity frameworks, especially in the finance, healthcare, and critical infrastructure industries.
