  Anonymous Server-Aided Verification

  • March 30, 2018

  • Inria Center of the University of Rennes - - Room TBD

  Speaker : par Elena Pagnin (Chalmers University of Technology, Sweden)

  Server-Aided Verification (SAV) is a method that can be employed to speed up the process of verifying signatures by letting the verifier outsource part of its computation load to a third party. Achieving fast and reliable verification under the presence of an untrusted server is an attractive goal in cloud computing and internet of things scenarios.In this talk I will describe a simple and[…]

  Privacy in The 5G-AKA Authentication Protocol

  • January 18, 2019

  • Inria Center of the University of Rennes - - Room TBD

  Speaker : Adrien Koutsos (LSV)

  The 5G mobile communications standards are being finalized, and drafts are now available. This standard describes the 5G-AKA authentication and key exchange protocol. The previous version of AKA (3G and 4G) are well-known for their lack of privacy against an active adversary (e.g. a user can be massively tracked using IMSI-catcher). This new version of AKA tries to offer more privacy, notably[…]

  Built on sand: on the security of Collaborative Machine Learning

  • March 25, 2022

  • Inria Center of the University of Rennes - - Room TBD

  Speaker : Dario Pasquini (EPFL)

  This talk is about inaccurate assumptions, unrealistic trust models, and flawed methodologies affecting current collaborative machine learning techniques. In the presentation, we cover different security issues concerning both emerging approaches and well-established solutions in privacy-preserving collaborative machine learning. We start by discussing the inherent insecurity of Split Learning and[…]

  Intriguing Properties of Adversarial ML Attacks in the Problem Space

  • June 19, 2020

  • Inria Center of the University of Rennes - - Room TBD

  Speaker : Fabio Pierazzi (King’s College London)

  Recent research efforts on adversarial ML have investigated problem-space attacks, focusing on the generation of real evasive objects in domains where, unlike images, there is no clear inverse mapping to the feature space (e.g., software). However, the design, comparison, and real-world implications of problem-space attacks remain underexplored. In this talk, I will present two major contributions[…]

  DroidGuard: A Deep Dive into SafetyNet

  • January 06, 2023

  • Inria Center of the University of Rennes - - Room TBD

  Speaker : 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[…]
