Efficient lattice-based cryptography. [PDF]

This thesis advances practical lattice-based cryptography. We propose Swoosh, a post-quantum non-interactive key exchange analogous to the Diffie–Hellman, requiring fewer communication rounds than currently standardised schemes. We introduce Gandalf, a compact ring signature scheme tailored for small rings, reducing signature sizes by 50%.

Implementing Lattice-Based Cryptography

, 2022
The thesis is about implementation of LWE/MLWE encryption schemes in C++ and the use of the Number Theoretic Transform (NTT) in order to get faster mul- tiplication operations over certain rings. We explore how much speed up we get by using NTT in our different schemes, comparing performance of our NTT im- plementation with the MulMod function of the ...

The condition number associated with ideal lattices from odd prime degree cyclic number fields

Journal of Mathematical Cryptology
The condition number of a generator matrix of an ideal lattice derived from the ring of integers of an algebraic number field is an important quantity associated with the equivalence between two computational problems in lattice-based cryptography, the ...

Lattice-based threshold cryptography

, 2020
Ever since the appearance of quantum computers, prime factoring and discrete logarithm based cryptography has been put in question, giving birth to the so called post-quantum cryptography. The goal of this bachelor's degree thesis is to develop a post-quantum threshold cryptosystem, in particular based on Ring Learning with Errors, a lattice-based ...

Notes on Lattice-Based Cryptography

, 2022
Asymmetrisk kryptering er avhengig av antakelsen om at noen beregningsproblemer er vanskelige å løse. I 1994 viste Peter Shor at de to mest brukte beregningsproblemene, nemlig det diskrete logaritmeproblemet og primtallsfaktorisering, ikke lenger er vanskelige å løse når man bruker en kvantedatamaskin. Siden den gang har forskere jobbet med å finne nye

Embedded lattice-based cryptography

Cryptographie basée sur les réseaux euclidiens pour les systèmes embarqués Un ordinateur quantique suffisamment puissant pour exécuter l'algorithme de Shor pourrait voir le jour et ainsi menacer la sécurité apportée par la cryptographie asymétrique actuellement déployée.
