A Universal Composability analysis of Android Protected Confirmation
Speaker : Maïwenn Racouchot - CISPA
As phones are used for more and more sensitive operations (such as bank transfers for example), there is a great necessity to design and deploy protocols that can ensure the security of such transactions, even in cases when the phone has been compromised. In order to accomplish that, Android in collaboration with Google have worked on a protocol called Android Protected Confirmation. The idea[…]-

Post-quantum Group-based Cryptography
Speaker : Delaram Kahrobaei - The City University of New York
Group-based cryptography is a relatively new family in post-quantum cryptography, with high potential. I will give a general survey of the status of post-quantum group-based cryptography and present some recent results.In the second part of my talk, I speak about Post-quantum hash functions using special linear groups. This hash function is a generalization of Tillich-Zemor hash function as well[…] -
Approches humanitaires du risque numérique : accidents de sécurité et impératif de protection
Speaker : Laetitia Della Torre - Université de technologie de Compiègne
Les ONG clament qu’elles ne sont pas des cibles (« not a target »), et plaident pour un arrêt des enlèvements d’humanitaires et des bombardements d’hôpitaux. Ajoutons que ce slogan est maintenant décliné dans une version « modernisée » : les ONG ne sont pas des cibles numériques (« not a digital target »). Ce slogan constitue un appel à stopper les cyberopérations contre les ONG, qui sont[…]-

The influence of flicker noise on ring oscillator-based TRNGs
Speaker : Licinius-Pompiliu BENEA - Univ. Grenoble Alpes, CEA, LETI
Ring oscillators (ROs) are often used in true random number generators (TRNGs). The jitter of their clock signal, used as a source of randomness, stems from thermal and flicker noises. While thermal noise jitter is often identified as the main source of randomness, flicker noise jitter is not taken into account due to its autocorrelated nature which greatly complexifies modelling. However, it is a[…]-

Remote data extraction through retroreflector hardware implants
Speaker : François Sarrazin, Pierre Granier - University of Rennes, IETR (UMR 6164)
Electromagnetic leakage eavesdropping is an increasingly accessible attack vector due to the democratization of software-defined radio. "TEMPEST" attacks rely on passively listening to the unwanted electromagnetic emanations of a target (computer screen, low speed USB peripheral…) in order to retrieve the transmitted data. However, the range and properties of such leakages are unpredictable.[…]-

Safety-Security Convergence of Industrial Control Systems
Speaker : Maxime Puys - Université Clermont Auvergne - IUT de Clermont-Ferrand
Industrial Control Systems (ICS) are designed to provide a service, such as power generation or water treatment, while protecting people, assets, and the environment against hazards. However, ICS now integrate Information Technology (IT) and are interconnected with the outside world such as the Internet, thereby exposing their infrastructures to cyberattacks. Cyberattacks have thus become new[…]-
