  An evaluation of Symbolic Execution Systems and the benefits of compilation with SymCC

  • 25 septembre 2020

  • Inria Center of the University of Rennes - - See the page of each talk for the room.

  Orateur : 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[…]

  On MILP modelisations

  • 29 avril 2022

  • Inria Center of the University of Rennes - - See the page of each talk for the room.

  Orateur : 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[…]

  Browser fingerprinting: past, present and possible future

  • 21 janvier 2022

  Orateur : Pierre Laperdrix (CRIStAL)

  Browser fingerprinting has grown a lot since its debut in 2010. By collecting specific information in the browser, one can learn a lot about a device and its configuration. It has been shown in previous studies that it can even be used to track users online, bypassing current tracking methods like cookies. In this presentation, we will look at how this technique works and present an overview of[…]

  Intrusion Detection Systems over an Encrypted Traffic: Problem and Solutions

  • 06 décembre 2019

  • Inria Center of the University of Rennes - - See the page of each talk for the room.

  Orateur : Sébastien Canard (Orange)

  Privacy and data confidentiality are today at the heart of many discussions. But such data protection should not be done at the detriment of other security aspects. In the context of network traffic, intrusion detection system becomes in particular totally blind when the traffic is encrypted, making clients again vulnerable to known threats and attacks. Reconciling security and privacy is then one[…]

  DroidGuard: A Deep Dive into SafetyNet

  • 06 janvier 2023

  • Inria Center of the University of Rennes - - See the page of each talk for the room.

  Orateur : Romain Thomas (Quarkslab)

  SafetyNet is the Android component developed by Google to verify the devices’ integrity. These checks are used by the developers to prevent running applications on devices that would not meet security requirements but it is also used by Google to prevent bots, fraud and abuse.In 2017, Collin Mulliner & John Kozyrakis made one of the first public presentations about SafetyNet and a glimpse into the[…]

  Squirrel: a new approach to computer-assisted proofs of protocols in the computational model.

  • 16 avril 2021

  • Inria Center of the University of Rennes - - See the page of each talk for the room.

  Orateur : David Baelde (ENS Cachan)

  Formal methods have brought several approaches for proving that security protocols ensure the expected security and privacy properties. Most of the resulting tools analyze protocols in symbolic models, aka. Dolev-Yao-style models. Security in the symbolic model does not imply security in the cryptographer’s standard model, the computational model, where attackers are arbitrary (PPTIME) Turing[…]
