Lattice-Based Cryptography: Principles and Applications in Post-Quantum Standards

Explore the principles of lattice-based cryptography in this 41-minute conference talk from the 2023 Post-Quantum Cryptography Conference in Amsterdam. Presented by Léo Ducas, a researcher at Centrum Wiskunde & Informatica (CWI) and Professor at Leiden University, the talk delves into the foundations of lattices, which underpin three of the four new PQC standards set by NIST: Kyber, Dilithium, and Falcon. Gain insights into the nature of lattices, the computational processes involved, and the challenges associated with implementing lattice-based schemes. Learn about both public key encryption and digital signatures in the context of lattice-based cryptography. This comprehensive overview is essential for those interested in understanding the future of cryptographic systems in a post-quantum world.
