Book ChapterDOI
Lattice Signatures and Bimodal Gaussians
TL;DR: In this article, a lattice-based digital signature scheme was proposed that represents an improvement, both in theory and in practice, over today's most efficient lattice primitives.
Book ChapterDOI
FHEW: Bootstrapping Homomorphic Encryption in Less Than a Second
Léo Ducas,Daniele Micciancio +1 more
TL;DR: A new method to homomorphically compute simple bit operations, and refresh (bootstrap) the resulting output, which runs on a personal computer in just about half a second, and is presented on the performance of the prototype implementation.
Proceedings Article
Post-quantum key exchange: a new hope
TL;DR: New parameters and a better suited error distribution are proposed, the scheme's hardness against attacks by quantum computers is analyzed in a conservative way, a new and more efficient error-reconciliation mechanism is introduced, and a defense against backdoors and all-for-the-price-of-one attacks is proposed.
Proceedings ArticleDOI
CRYSTALS - Kyber: A CCA-Secure Module-Lattice-Based KEM
Joppe W. Bos,Léo Ducas,Eike Kiltz,Tancrède Lepoint,Vadim Lyubashevsky,John M. Schanck,Peter Schwabe,Gregor Seiler,Damien Stehlé +8 more
TL;DR: This paper introduces Kyber, a portfolio of post-quantum cryptographic primitives built around a key-encapsulation mechanism (KEM), based on hardness assumptions over module lattices, and introduces a CPA-secure public-key encryption scheme and eventually construct, in a black-box manner, CCA-secure encryption, key exchange, and authenticated-key-exchange schemes.
Journal ArticleDOI
CRYSTALS-Dilithium: A lattice-based digital signature scheme
Léo Ducas,Eike Kiltz,Tancrède Lepoint,Vadim Lyubashevsky,Peter Schwabe,Gregor Seiler,Damien Stehlé +6 more
TL;DR: This paper presents the lattice-based signature scheme Dilithium, which is a component of the CRYSTALS (Cryptographic Suite for Algebraic Lattices) suite that was submitted to NIST’s call for post-quantum cryptographic standards.
