Effects of synchronous clock glitch effect on the security of an integrated circuit
PhD : Amélie MAROTTA, Centre Inria de l'Université de Rennes, IRISA Context: the various sources of security vulnerability Fault injection is part of a bigger ecosystem of vulnerability exploitation methods, which it can be paired with. To make the study of the security challenges of electronic devices easier, we define three sources of vulnerabilities : software, microarchitectural, and physical[…] -

Prise de contrôle d’un infodivertissement automobile à distance
Orateur : 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[…]-

Empower New Code Citizens to Reflect and Communicate on Code Security
Orateur : Manuel Maarek - Heriot-Watt University
Creating secure software code requires software engineers to elicit and follow the security requirements of the system they are building. Software engineer teams might not have the security expertise to approach this angle of software development confidently. With the democratisation of access to software development and deployment, software are often built by developers with neither software[…] -

A non-comparison oblivious sort and its application to private k-NN
Orateur : Sofiane Azogagh - UQÀM
Sorting is a fundamental subroutine of many algorithms and as such has been studied for decades. A well-known result is the Lower Bound Theorem, which states that no comparison-based sorting algorithm can do better than O(nlog(n)) in the worst case. However, in the fifties, new sorting algorithms that do not rely on comparisons were introduced such as counting sort, which can run in linear time[…]-

[CANCELLED] Black-Box Collision Attacks on Widely Deployed Perceptual Hash Functions and Their Consequences
Orateur : Diane Leblanc-Albarel - KU Leuven
[CANCELLED] Perceptual hash functions identify multimedia content by mapping similar inputs to similar outputs. They are widely used for detecting copyright violations and illegal content but lack transparency, as their design details are typically kept secret. Governments are considering extending the application of these functions to Client-Side Scanning (CSS) for end-to-end encrypted services:[…]-

Conformité TEMPEST et compromission d’information au travers de l’arbre d’alimentation d’un équipement
Orateur : 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,[…] -
