Description
With the widespread development of artifical intelligence, Deep Neural Networks (DNN) have become valuable intellectual property (IP). In the past few years, software and hardware-based attacks targetting at the weights of the DNN have been introduced allowing potential attacker to gain access to a near-perfect copy of the victim's model. However, these attacks either fail against more complex architecture or loose in fidelity regarding the targeted model. In this talk, I will present a new attack methodology combining side-channels attacks with software attacks in order to extract more complex DNN. First, I will present the main methodologies from the state of the art, and the comparison that can be made with traditional cryptanalytic attacks. I will then describe how side-channel attacks can help with the current limitations and introduce our framework as well as our experimental results. This talk will be concluded by the presentation of some potentials future work.

CHERI: Architectural Support for Memory Protection and Software Compartmentalization
Speaker : Robert Watson - University of Cambridge
CHERI is a processor architecture protection model enabling fine-grained C/C++ memory protection and scalable software compartmentalization. CHERI hybridizes conventional processor, instruction-set, and software designs with an architectural capability model. Originating in DARPA’s CRASH research program in 2010, the work has progressed from FPGA prototypes to the recently released Arm Morello[…]-

CHERI standardization and software ecosystem
Speaker : Carl SHAW - CODASIP
This talk will describe the current status of the RISC-V International standardization process to add CHERI as an official extension to RISC-V. It will then explore the current state of CHERI-enabled operating systems, toolchains and software tool development, focusing on the CHERI-RISC-V hardware implementations of CHERI. It will then go on to give likely future development roadmaps and how the[…]-

PhaseSCA: Exploiting Phase-Modulated Emanations in Side Channels
Speaker : Pierre Ayoub - LAAS-CNRS
In recent years, the limits of electromagnetic side-channel attacks have been significantly expanded.However, while there is a growing literature on increasing attack distance or performance, the discovery of new phenomenons about compromising electromagnetic emanations remains limited. In this work, we identify a novel form of modulation produced by unintentional electromagnetic emanations: phase[…]-

Conformité TEMPEST et compromission d’information au travers de l’arbre d’alimentation d’un équipement
Speaker : Tristan PECHERAU, David HARDY - Thalès
THALES conçoit des équipements cryptographiques et de radiocommunication tactiques, navales et aéronautiques, embarquant des éléments de chiffrement pour la sécurité des communications. Cette sécurité notamment d’un point de vue des émanations électromagnétiques est normée. Ces normes de sécurité de l’information, sont connues sous le nom de code “TEMPEST”, correspondant aux normes OTAN SDIP-27,[…] -
Prise de contrôle d’un infodivertissement automobile à distance
Speaker : Philippe Trebuchet, Guillaume Bouffard - ANSSI
Les véhicules connectés intègrent de nombreuses technologies de communications sans-fil à distance, comme celles exploitant les protocoles Bluetooth ou WiFi. Si le gain en confort d’utilisation et d’interaction est notable, la mise à disposition de ce type d’interfaces augmente les risques en matière de cybersécurité. Dans cet article, nous analysons l’implémentation de la pile Bluetooth embarquée[…]-
