Post-Quantum Cryptography Explained: Kyber & Dilithium 🛡️

Dive into the future of security with V1a: Post-quantum Cryptography, the first video in Alfred Menezes's free course "Kyber and Dilithium", exploring cutting-edge lattice-based cryptographic schemes standardized by NIST on August 13, 2024. In this video, we unpack the basics of post-quantum cryptography (PQC), designed to secure data against quantum computers and Shor’s algorithm. We introduce the core concepts of PQC, why quantum threats to classical encryption—like Grover's search—demand new solutions, and how lattice-based cryptography rises to the challenge.

Ideal for undergraduate and graduate students, applied cryptographers, security engineers, and cybersecurity professionals, this course provides a high-level understanding of PQC, covering key topics like PQC standardization, Kyber-KEM, and Dilithium ML-DSA. As you’ll learn, these schemes are integral to the CNSA 2.0 suite, providing secure, scalable encryption and authentication in the post-quantum era.

Build a solid foundation in post-quantum cryptography and keep pace with evolving security standards. Whether you're new to cryptography or deepening your expertise, this series is your gateway to the world of quantum-resistant encryption.
