Post-Quantum Cryptography
Post-Quantum Cryptography (PQC) represents the next generation of encryption algorithms designed to resist attacks from quantum computers while remaining secure against classical attacks.
What is Post-Quantum Cryptography?
Current public-key cryptography (RSA, ECC, Diffie-Hellman) relies on mathematical problems that quantum computers can solve efficiently using Shor's algorithm.
PQC uses different mathematical foundations—like lattice problems, hash functions, and code-based systems—that are believed to be resistant to both classical and quantum attacks.
In 2024, NIST finalized the first set of PQC standards, marking a critical milestone in the global transition to quantum-safe security.
Why It Matters
- →Quantum computers will break current encryption
- →Data encrypted today could be decrypted in the future
- →Migration to PQC takes years—planning must start now
- →Regulatory requirements are emerging globally

Building for the Quantum Era
While PQC represents our vision for the future, we recognize that organizations face immediate security challenges today. That's why we've started with KnowSpams—addressing the human factor that causes 95% of breaches.
Our research team continuously explores PQC integration opportunities, ensuring our roadmap aligns with NIST standards and emerging best practices. When the time is right, we'll bring quantum-resilient products to market.
This pragmatic approach—solving today's problems while preparing for tomorrow—is what sets Quantam Secure apart.
