Launching LMF - the Formal Methods Laboratory

The Laboratoire Méthodes Formelles (LMF) was founded on 1 January 2021 as a joint research centre of University Paris-Saclay, CNRS, ENS Paris-Saclay, Inria, and CentraleSupélec with a main focus on formal methods. The new laboratory combines the expertise of about 100 members from the former Laboratoire Spécification et Vérification (LSV) and the VALS team of Laboratoire de Recherche en Informatique (LRI).

In our mission to enlighten the digital world through Mathematical Logic, we rely on formal methods as a tool to analyse, model, and reason about computing systems, such as computer programs, security protocols, and hardware designs. Our research targets a wide range of computational paradigms, from classical to emerging ones such as biological and quantum computing.

LMF is structured around three hubs: Proofs and Models, which lie at the heart of our historical background, and Interactions, that is aimed at fostering cross-fertilisation between formal methods and other domains in computing science and beyond.

Abstract: This thesis is at the crossroad of verification and synthesis of parameterized concurrent systems. The parameterized model checking problem asks whether a system satisfies a given specification independently of the number of its components, whereas synthesis requires an algorithmic design of protocols for its components so that the specification is satisfied.Read more...

Caroline Fontaine Takes the Lead of the CNRS Research Network on Computer Security

Caroline Fontaine has been appointed director of the CNRS Research Network on Computer Security GdR Securité Informatique in Summer 2021. The network federates the French research groups working on cryptography, formal methods for security, privacy, security of hardware, software, data and networks.

The photo shows Caroline at the International Cybersecurity Forum (FIC) on 7 - 9 September in Lille, where she presented the actions of the Network.

Best-Paper Award at FMICS 2021

Cláudio Belo Lourenço and Claude Marché from the Toccata team at LMF with co-authors from Mitsubishi Electric received the Best-Paper Award at FMICS 2021, the 26th International Conference on Formal Methods for Industrial Critical Systems.

Their contribution Automated Verification of Temporal Properties of Ladder Programs was valued by the jury as a "good example for how formal methods can be used in industrial applications" with "industrial interest for both legacy Ladder programs and programs to be developed".

FMICS 2021 was held as part of the QONFEST event that federated four main venues in the area of formal methods.

Towards Security-Oriented Program analysis

Speaker: Sébatien Bardin, CEA, Paris-Saclay

Tuesday 7 September 2021, 11:00, (amphi 1Z53, ENS Paris-Saclay)

Abstract: While digital security concerns increase, we face both a urging demand for more and more code-level security analysis and a shortage of security experts. Hence the need for techniques and tools able to automate part of these code-level security analyses. As source-level program analysis and formal methods for safety-critical applications have made tremendous progress in the past decades, it is extremely tempting to adapt them from safety to security. Yet, security is not safety and, while still useful, a direct adaptation of safety-oriented program analysis to security scenarios remains limited in its scope. In this talk, we will argue for the need of security-oriented program analysis. We will first present some of the new challenges faced by formal methods and program analysis in the context of code-level security scenarios. For example, security-oriented code analysis is better performed at the binary level, the attacker must be taken into account and practical security properties deviate from standard reachability / invariance properties. Second, we will discuss some early results and achievements carried out within the BINSEC group at CEA LIST. Especially, we will show how techniques such as symbolic execution and SMT constraint solving can be tailored to a number of practical code-level security scenarios.
