ECDSA White-Box Implementations, Feedback on CHES 2021 WhibOx Contest
Speaker : Agathe Houzelot - Idemia
Cryptographic algorithms are primarily designed to be secure in the black-box model, where an attacker can only observe their input/output behavior. However in practice, algorithms are rarely executed in a completely isolated environment and additional information is often leaked. In the context of mobile applications or connected objects, devices often lack secure storage to protect secret keys,[…] -

Correction of dual lattice attacks
Speaker : Kevin Carrier - CY Cergy
The security of cryptographic systems such as Kyber and Dilithium (currently undergoing standardization by NIST) fundamentally hinges on the Learning With Errors (LWE) problem. However, the state of the art for attacking this problem is not yet entirely clear. Specifically, the validity of dual attacks on LWE is currently under scrutiny due to their analyses relying on heuristics that have proven[…] -

SCA-LDPC: A Code-Based Framework for Key-Recovery Side-Channel Attacks on Post-Quantum Encryption Schemes
Speaker : Denis Nabokov - Université de Lund
Whereas theoretical attacks on standardized crypto primitives rarely lead to actual practical attacks, the situation is different for side-channel attacks. Improvements in the performance of side-channel attacks are of utmost importance. In this paper, we propose a framework to be used in key-recovery side-channel attacks on CCA-secure post-quantum encryption schemes. The basic idea is to[…] -

Password-Authenticated Key Exchange (PAKE) from Isogenies
Speaker : Sabrina Kunzweiler - Université Bordeaux
The passwords that we use in our everyday life are often chosen to be easily memorable which makes them vulnerable to attacks. This problem is addressed by password-authenticated key exchange (PAKE). The general idea is to enable two parties who share the same (potentially weak) password to establish a strong session key. Most PAKE protocols used today are based on Diffie-Hellman key exchange in[…] -

Modélisation statistique et sécurité des générateurs d'aléa pour la cryptographie
Speaker : David Lubicz - DGA, IRMAR
Dans cet exposé on essaie d'expliquer ce que l'on entend pas méthodes statistiques et on donne des exemples concrets d'application dans la cybersécurité.-
