Cryptanalysis of a privacy-preserving authentication scheme based on private set intersection

open access: yesJournal of Mathematical Cryptology
Continuous and context-aware authentication mechanisms have been proposed as complementary security mechanisms to password-based authentication for computer devices that are handled directly by humans, such as smart phones. Such authentication mechanisms

Constructions of advanced cryptographic primitives

open access: yes, 2023
Dans cette thèse, nous proposons des constructions efficaces de primitives cryptographiques avec des fonctionnalités avancées. Nous nous concentrons sur des primitives qui permettent des applications préservant la confidentialité, telles que la recherche sur des données chiffrées ou le vote électronique, avec une sécurité prouvable dans le modèle de l ...

Analysis of recent cryptographic primitives

open access: yes, 2016
In this thesis, we study the security of some recent cryptographic primitives, both symmetric and asymmetric. Along the way we also consider white-box primitives, which may be regarded as a middle ground between symmetric and asymmetric cryptography. We begin by showing the existence of non-trivial linear maps commuting with the round function of some ...

Cryptographic Primitives with Quasigroup Transformations

open access: yes, 2010
AMS Subj. Classification: Primary 20N05, Secondary 94A60 The intention of this research is to justify deployment of quasigroups in cryptography, especially with new quasigroup based cryptographic hash function NaSHA as a runner in the First round of the ongoing NIST SHA-3 competition.
