An Introduction to Post-Quantum Cryptography for Linux System Administrators

This beginner-friendly session will first introduce the basics of quantum computing and explain why it poses a threat to current public-key algorithms such as RSA, DSA, and ECC. Next, we’ll explore at a high level post-quantum cryptographic algorithms—specifically, lattice-based, hash-based, and code-based encryption schemes—that are being considered as replacements for today’s standards. Participants will learn about open-source libraries and tools that already support post-quantum algorithms, along with their compatibility with widely used Linux services.
