Reasoning over leaks of information for Access Control of Databases
Speaker : Pierre Bourhis (CNRS, CRISTAL)
Controlling the access of data in Database management systems is a classical problem and it has been solved through different mechanisms. One of the most common mechanism implemented in most Database management systems is the mechanism of views, i.e defining the accessible data of a user as the result of a query. This mechanism is also used in principle in other systems such as in social networks.[…] -

Les cyberopérations: entre technique et droit international. Attribution, preuve et responsabilité.
Speaker : Anne-Thida Norodom (Professeur de droit public, Université de Paris)
L’objet de cette intervention est de montrer à quel point le juridique est dépendant du technique lorsqu’il s’agit de réguler les cyberopérations. L’approche choisie sera celle du droit international public, c’est-à-dire du droit applicable entre Etats. Alors qu’il existe un consensus au niveau international sur l’applicabilité du droit international dans le domaine numérique, les négociations en[…] -

On MILP modelisations
Speaker : Christina Boura (UVSQ, CNRS, LMV)
Modelizing a problem using linear constraints and solving it by some Mixed Integer Linear Programming (MILP) solver is a popular approach in many domains of computer science. In this talk we present and compare different new techniques to modelize any subset of {0,1}^n for MILP. We then discuss the efficiency of our models by applying them to the search of differential paths, a classical problem[…] -

An evaluation of Symbolic Execution Systems and the benefits of compilation with SymCC
Speaker : Aurélien Francillon (Eurecom)
In this talk I will discuss our recent work, together with Sebastian Poeplau, on Symbolic execution. Symbolic execution has become a popular technique for software testing and vulnerability detection, in particular, because it allows to generate test cases for difficult to reach program paths. However, a major impediment to practical symbolic execution is speed, especially when compared to near[…] -

Bridging Deep Learning and Classical Profiled Side-Channel Attacks
Speaker : Gabriel Zaid
Over the recent years, the cryptanalysis community leveraged the potential of research on Deep Learning to enhance attacks. In particular, several studies have recently highlighted the benefits of Deep Learning based Side-Channel Attacks (DLSCA) to target real-world cryptographic implementations. While this new research area on applied cryptography provides impressive result to recover a secret[…] -

Challenges related to random number generation for cryptographic applications
Speaker : Elie Noumon Allini
The main purpose of cryptography is to ensure secure communication. In order to achieve this goal, cryptographic schemes make an intensive use of random numbers. Given that the security of these schemes highly depends on these numbers, it is important to produce high-quality random numbers. Knowing that most cryptographic modules are nowadays implemented in logic devices, we investigated True[…] -
