Tight Leakage-Resilient CCA-Security from Quasi-Adaptive Hash Proof System

2019
We propose the concept of quasi-adaptive hash proof system (QAHPS), where the projection key is allowed to depend on the specific language for which hash values are computed. We formalize leakage-resilient(LR)-ardency for QAHPS by defining two statistical properties, including LR-\(\langle \mathscr {L}_0, \mathscr {L}_1 \rangle \)-universal and LR ...

Contribution à la cryptographie post-quantique basée sur les codes correcteurs d’erreurs en métrique rang : Hash Proof Systems et cryptographie à bas coût

La conception d’ordinateurs quantiques aura un impact majeur sur la cryptographie que nous utilisons tous les jours pour sécuriser nos communications, en particulier sur la cryptographie dite asymétrique. De plus, la multiplication des objets connectés dans notre quotidien et leurs limitations en terme de capacité de calcul et de mémoire disponible en ...
