In this article, we generalize the works of Pan et al.(Eurocrypt'21) and Porter et al.(ArXiv'21)
and provide a simple condition under which an ideal lattice defines an easy instance of the …

PASS Encrypt is a lattice-based public key encryption scheme introduced by Hoffstein and
Silverman (Des Codes Cryptogr 77 (2–3): 541–552, 2015). The efficiency and algebraic …

Abstract The Partial Vandermonde (PV) Knapsack problem is an algebraic variant of the low-
density inhomogeneous SIS problem. The problem has been used as a building block for …

We describe a fault attack against the deterministic variant of the FALCON signature
scheme. It is the first fault attack that exploits specific properties of deterministic FALCON …

In this study, we revisit the RSA public key cryptosystem in some special case of Boneh and
Durfee's attack when the private key d assumes to be larger than the public key e. The attack …

Remote communications are taking more and more importance in our everyday lives: from
accessing our bank accounts and health data, communicating with family, friends and co …

Dans cette thèse, nous nous intéressons à la cryptographie fondée sur les codes
correcteurs d'erreurs, et plus particulièrement sur ceux possédant une forte structure …

The main focus of this Ph. D thesis lies on the computational problem Learning With Errors
(LWE). It is a core building block of lattice-based cryptography, which itself is among the …
