  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[…]

  Privacy in The 5G-AKA Authentication Protocol

  • 18 janvier 2019

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

  Orateur : 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[…]

  Search-Based Local Black-Box Deobfuscation: Understand, Improve and Mitigate

  • 25 février 2022

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

  Orateur : Grégoire Menguy (CEA LIST)

  Code obfuscation aims at protecting Intellectual Property and other secrets embedded into software from being retrieved. Recent works leverage advances in artificial intelligence (AI) with the hope of getting blackbox deobfuscators completely immune to standard (whitebox) protection mechanisms. While promising, this new field of AI-based, and more specifically search-based blackbox deobfuscation,[…]
