Generic SCARE: reverse engineering without knowing the algorithm nor the machine
Orateur : Hélène LE BOUDER - IMT Atlantique
A novel side-channel-based reverse engineering technique is introduced, capable of reconstructing a procedure solely from inputs, outputs, and traces of execution. Beyond generic restrictions, no prior knowledge of the procedure or the chip it operates on is assumed. These restrictions confine the analysis to 8-bit RISC constant-time software implementations. Specifically, the feasibility of[…] -

Machine Learning for Computer Security Detection Systems: Practical Feedback and Solutions
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
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
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[…] -
