Post-Quantum Cryptography: The Global Race to Secure Our Digital Future 🔐

A global race is underway to replace the foundations of our digital security before quantum computers break encryption as we know it. This is the story of post-quantum cryptography (PQC)—the silent revolution to make our world quantum-safe.
In this video, we explore:
✅ The Threat: "Harvest Now, Decrypt Later" attacks—where adversaries store encrypted data today, waiting for quantum computers to unlock it tomorrow.
✅ The Quantum Threat: How Shor’s Algorithm turns today’s unbreakable encryption (RSA, ECC) into child’s play for quantum computers.
✅ The Global Response: How NIST’s Post-Quantum Cryptography Project—a 6-year competition—led to breakthroughs like CRYSTALS-Kyber and CRYSTALS-Dilithium.
✅ The New Math: How lattice-based cryptography and other quantum-resistant algorithms work on today’s computers but defy future quantum attacks.
✅ The Stakes: Why 6G, AI, and immersive tech depend on PQC—and how governments (like the NSA) are racing to adopt it by 2025-2030.
✅ The Challenge: Upgrading the entire planet’s security infrastructure—the biggest tech migration in history.
This isn’t science fiction—it’s happening right now. The question isn’t if we’ll switch to PQC, but how fast we can do it before quantum computers arrive.
