What Is PQC – Post-Quantum Cryptography?

PQC is a post-quantum cryptographic algorithm with NIST PQC studies as reference.

It is designed to replace traditional RSA-based systems with a stronger, quantum resistant transport layer. It leverages mathematical functions selected by NIST that are significantly harder to reverse-engineer compared to prime factorization and elliptic curve-based systems currently used in PKI.

In response, post-quantum cryptography (PQC) has emerged as a field devoted to developing quantum-resistant algorithms. Modern PQC implementations demand not only algorithmic resilience but also entropy sources which are immune to quantum accelerated bias exploitation.

NIST began working on post-quantum algorithms in 2014. By July 2020, after the third round of evaluations, NIST narrowed the field to seven finalists and eight alternate algorithms. We selected lattice-based algorithms—recognized for their superior security—for use in PQC. As NIST’s standards evolve, PQC will seamlessly adapt without impacting ongoing operations.

What is Q-Day

Organizations that utilize computers and networks are under Q-Day threat. Q-Day is themoment when Quantum computers can break today’s encryption. Data is your mostvaluable asset. Sensitive information often needs to be protected for 10+ years, and in manycases, 25 years. The risk of waiting is high. Transitioning to post-quantum Cryptography isthe best way to protect data in the future, as well as now.

Why is PQC needed for Crypto agility

Digital transformation is changing with external risks, and quantum technology. Security systems need to change with the technology they are protecting.

PQC (PQC) supports seamless integration with existing and future infrastructure. It adheres to NIST standards for ease of deployment assuring compatibility and agility while minimizing disruption during transition.

Frequently Asked Questions

PQC uses quantum-resistant algorithms, protecting sensitive government and telecom data from future quantum attacks. It ensures ongoing confidentiality and security as cyber threats evolve.

Adversaries may capture encrypted data now to decrypt later with quantum tech; early PQC adoption secures information over decades and prevents future breaches on “Q-Day”.

PQC based on NIST standards enables crypto-agile, seamless upgrades that don’t disrupt existing telecom or government operations or require expensive equipment replacements.

Federal agencies like NIST and NSA have set phased plans: identify vulnerable crypto, create migration strategies, and coordinate prioritized secure upgrades across all critical networks.

Inventory cryptographic assets, align with NIST, draft a migration plan, educate leadership, and run PQC pilots ensuring strategic, phased quantum-readiness.
