Post-Doctorant F/H Towards a generalization of cryptanalysis families
Contract type : Fixed-term contract
Renewable contract : Yes
Level of qualifications required : PhD or equivalent
Fonction : Post-Doctoral Research Visit
Context
Inria Paris, Epi Cosmiq.
Assignment
Cryptanalysis is the foundation of the confidence we have in the cryptographic
primitives we use: trying to break them and determining their security margins
are fundamental tasks in order to understand the security they can offer.
Symmetric cryptanalysis is a very active and innovative field. There are
several families of attacks, the main ones being differential [3] and linear [7], but
many others exist and they have all profited from many evolutions through the
last years, like MITM (meet-in-the-middle) attacks and their variants (see [6]),
differential-linear attacks [1], impossible differential attacks [2, 5] each providing
the best results on different constructions.
A new type of attack, differential meet-in-the-middle attacks, was proposed in
Crypto 2023 [4], and a recent work under submission proposes some interesting
extensions, like using structures to increase the number of attacked rounds.
During the post doc we will study its automamization and generalization of the state test technique.
