  Voting : You Can’t Have Privacy without Individual Verifiability

  • 01 mars 2019

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

  Orateur : Joseph Lallemand (Loria)

  Electronic voting typically aims at two main security goals: vote privacy and verifiability. These two goals are often seen as antagonistic and some national agencies even impose a hierarchy between them: first privacy, and then verifiability as an additional feature. Verifiability typically includes individual verifiability (a voter can check that her ballot is counted); universal verifiability […]

  Binary Edwards Curves for intrinsically secure ECC implementations for the IoT

  • 07 septembre 2018

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

  Orateur : Antoine Loiseau (CEA)

  Even if recent advances in public key cryptography tend to focus on algorithms able to survive the post quantum era, at present, there is a urgent need to propose fast, low power and securely implemented cryptography to address the immediate security challenges of the IoT. In this talk, we present a new set of Binary Edwards Curves which have been defined to achieve the highest security levels (up[…]

  DroidGuard: A Deep Dive into SafetyNet

  • 06 janvier 2023

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

  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[…]

  Browser fingerprinting: past, present and possible future

  • 21 janvier 2022

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

  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 - - Room TBD

  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[…]

  Private Set Intersection and Other Private Information Sharing Protocols

  • 07 novembre 2022

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

  Orateur : Xavier Carpent (University of Nottingham)

  In this seminar, we will give an overview of Private Set Intersection (PSI), some of its constructions, use cases, and open research questions. The canonical PSI protocol allows Alice and Bob (both with their own set of elements) to interact in a way that Alice learns the intersection of the sets and nothing else. Numerous variants exist:cardinality of intersection only (how many elements in[…]
