Building Intuition for Lattice-Based Signatures – Part 2: Fiat-Shamir with Aborts

Introduction This two-part blog series aims to build some intuition for the main techniques that are used to construct lattice-based signatures, focusing in particular on the techniques underlying Falcon and Dilithium, the two lattice-based signature schemes selected for standardization by the National Institute of Standards and Technology (NIST). In part 1 of this two-part blog […]
