Abstract: The design and analysis of low-level computing devices directly implemented in hardware is commonly based on finite state machine models. In this work we review some of the assumptions made in these designs and discuss techniques for the cases where the assumptions fail to hold. Read more...

Abstract: The automatic generation of tests is a major issue in software engineering and security. Test suites created this way can efficiently explore the code, and find potential bugs, and therefore vulnerabilities.

In this thesis, we were interested in two of the said techniques: symbolic execution and fuzz testing. Read more...

Abstract: Dynamical systems have a major impact on human development, especially critical systems that can put human lives at risk if something goes wrong. Hence, the need of studying the behavior of these systems to guarantee their correct functioning. Nevertheless, computing such type of system has never been an easy task, as the complexity of these systems is constantly increasing, in addition to the perturbations that may arise during their operation, as well as undefined parameters that may exist. To ensure that a system always produces the expected results and does not fail in any way, a formal verification of its behavior and properties is necessary.

In this thesis, we study dynamical systems from different perspectives and using various techniques. More specifically, we focus on the formal verification of critical properties such as schedulability, synchronization, robustness and stability.

Matthias Függer et al: new article in JACM

How fast can you converge towards a consensus value?

In their recent work, Matthias Fuegger (LMF), Thomas Nowak (LISN), and Manfred Schwarz (TU Wien) study this question in distributed systems where nodes start from an initial value and seek to converge towards a common consensus value. The paper shows that deceptively simple algorithms are optimal and provides tight lower bounds.

Journées du GT Verif

ENS Paris-Saclay

Les Journées du GT Vérification du GDR IM ont lieu les 17, 18 et 19 novembre 2021 au Laboratoire Méthodes Formelles, ENS Paris-Saclay, à Gif-sur-Yvette.

Elles visent à rassembler la communauté française en vérification formelle, et en particulier les chercheurs juniors, doctorants et post-doctorants, avec pour objectif de favoriser les collaborations et l'ouverture sur des thématiques liées à la vérification. Elles ont pour ambition de couvrir tous les domaines de la vérification formelle.
