Post-Quantum Cryptography Explained: The Future of Secure Communications 🔐

Welcome to Lesson 3.7.1 of the CompTIA SecurityX CAS-005 series. In this video, we explore Post-Quantum Cryptography (PQC) — what it is, why it's essential, and how it compares to classical cryptographic methods like Diffie-Hellman and Elliptic Curve Cryptography (ECC).

We cover:

The risk quantum computing poses to current cryptography

Differences between PQC and traditional methods like DH & ECC

Quantum-resistant algorithms: Kyber, Dilithium, SPHINCS+

Real-world examples and NIST standardization efforts

How to prepare your security architecture for the post-quantum world

This is part of Domain 3.0 – Security Architecture in the CAS-005 exam.
