PhD Position F/M Estimating precisely the efficiency of cryptanalysis techniques for symmetric primitives intended for advanced protocols
Contract type : Fixed-term contract
Level of qualifications required : Graduate degree or equivalent
Fonction : PhD Position
Context
This thesis will be co-supervised by Yann Rotella (UVSQ) and Léo Perrin (COSMIQ, Inria). It will be financed by the ERC project ReSCALE, and will take place at the "centre Inria de Paris", within the COSMIQ team.
Assignment
The candidate will be expected to do research on both the theoretical and the practical (i.e. implementation) aspects of various cryptanalysis techniques that are of particular relevance when analysing symmetric primitives intended for advanced protocols.
Main activities
The aim of this thesis is to precisely understand how the complexity of some cryptanalysis techniques scales with the various parameters of a cryptosystem.
The candidate will then be expected to investigate this topic, publish scientific papers (and possibly computer programs) describing their results, and to present them at the relevant conferences or seminars.
