  A Formal Analysis of 5G Authentication

  • 03 juin 2019

  • Inria Center of the University of Rennes - - Petri/Turing room

  Orateur : Sasa Radomirovic (University of Dundee)

  Mobile communication networks connect much of the world’s population. The security of users’ calls, text messages, and mobile data depends on the guarantees provided by the Authenticated Key Exchange protocols used. For the next-generation network (5G), the 3GPP group has standardized the 5G AKA protocol for this purpose.In this talk, I will report on our formalization of the 5G standard’s AKA[…]

  Machine Learning for Computer Security Detection Systems: Practical Feedback and Solutions

  • 30 novembre 2018

  • Inria Center of the University of Rennes - - Petri/Turing room

  Orateur : Anaël Beaugnon (ANSSI)

  Machine learning based detection models can strengthen detection, but there remain some significant barriers to the widespread deployment of such techniques in operational detection systems. In this presentation, we identify the main challenges to overcome and we provide both methodological guidance and practical solutions to address them. The solutions we present are completely generic to be[…]

  The Internet of Backdoors

  • 07 mars 2018

  • Inria Center of the University of Rennes - - Petri/Turing room

  Orateur : par Sam L. Thomas (University of Birmingham, UK)

  Complex embedded devices are becoming ever prevalent in our everyday lives, yet only a tiny amount of people consider the potential security and privacy implications of attaching such devices to our home, business and government networks. As demonstrated through recent publications from academia and blog posts from numerous industry figures, these devices are plagued by poor design choices[…]

  Subject Access Request and Proof of Ownership

  • 25 octobre 2019

  • Inria Center of the University of Rennes - - Petri/Turing room

  Orateur : Cédric Lauradoux (INRIA Rhône-Alpes)

  The GDPR (General Data Protection Regulation) provides rights on our data: access, rectification, objection, etc. However, this regulation is not binding on how we can exercise these rights. Data controllers have therefore deployed various methods to authenticate subject requests. We have analyzed how this authentication process can fail and examined its consequences. Our study shows that a key[…]

  Splitting the Linux Kernel for Fun and Profit

  • 07 décembre 2018

  • Inria Center of the University of Rennes - - Petri/Turing room

  Orateur : Chris Dalton (HP, Bristol, UK)

  This talk looks at a pragmatic attempt at strengthening the security properties of Linux by introducing a degree of intra-kernel protection into the Linux kernel (supported by CPU Virtualization silicon features). Consider it, if you like, an attempt at retrofitting a ‘micro-kernel’ interface into traditionally monolithic Linux whilst maintaining a single linux code base (yes it’s still Linux), no[…]

  Anonymous Server-Aided Verification

  • 30 mars 2018

  • Inria Center of the University of Rennes - - Petri/Turing room

  Orateur : 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[…]
