Kyber: Post-Quantum Cryptography Explained

In this group presentation, we explore CRYSTALS-Kyber (standardized by NIST as ML-KEM), a cutting-edge post-quantum cryptographic algorithm designed to resist quantum attacks. 🔍 We begin with an introduction to quantum computing and the growing need for post-quantum cryptography, especially as quantum advancements threaten traditional encryption methods like RSA and ECC through algorithms like Shor’s Algorithm. The presentation covers: 🧠 How Kyber works using lattice-based cryptography and Module Learning With Errors (MLWE) 💻 A practical live demo comparing Kyber’s performance with RSA 🌐 Real-world use cases and adoption in browsers, government, and tech platforms 📐 The mathematics behind Kyber, including polynomial operations and encryption/decryption with noise 🎓 Whether you're a cybersecurity student, cryptography enthusiast, or tech professional, this session will help you understand why Kyber is the leading choice for securing data in a post-quantum world. 📘 This presentation was submitted as part of the Master of Information and Cybersecurity (MICS) program at UC Berkeley.
