Title:
CRYSTALS – Dilithium: Digital Signatures from Module Lattices

Authors: Leo Ducas, Tancrede Lepoint, Vadim Lyubashevsky, Peter Schwabe, Gregor Seiler, Damien Stehle

Abstract:

This paper presents Dilithium, a lattice-based signature scheme that is part of the CRYSTALS (Cryptographic Suite for Algebraic Lattices) package that will be submitted to the NIST call for post-quantum standards. The scheme is designed to be simple to securely implement against side-channel attacks and to have comparable efficiency to the currently best lattice-based signature schemes. Our implementation results show that Dilithium is competitive with lattice schemes of the same security level and outperforms digital signature schemes based on other post-quantum assumptions.
