Low Memory Attacks on Small Key CSIDH

Sabrina Kunzweiler présentera ses travaux concernant la cryptographie post-quantique le lundi 25/03 à 14h en salle 301. La présentation se fera en anglais.

Abstract
Commutative Supersingular Isogeny Diffie-Hellman (CSIDH)  is a relatively new candidate in the field of post-quantum cryptography. This talk will provide an introduction to the original scheme, and a small key version proposed for high security parameters. In this setting, we will see that representation techniques (known from code and lattice based cryptography) need to be considered in the cryptanalysis.
The talk is based on a joint work Jesús-Javier Chi-Domínguez, Andre Esser and Alexander May.
