Discovering Lattice Reduction Strategies via Self-Play

Mohamed Malhou, Kristin Lauter, Ludovic Perret

The Lenstra-Lenstra-Lovász (LLL) algorithm is a seminal contribution to computer science used for lattice basis reduction, yet its polynomial-time outputs produce bases that are fa…

SALSA PICANTE: a machine learning attack on LWE with binary secrets

Cathy Li, Jana Sotáková, Emily Wenger +4

Learning with Errors (LWE) is a hard math problem underpinning many proposed post-quantum cryptographic (PQC) systems. The only PQC Key Exchange Mechanism (KEM) standardized by NIS…
