Post-quantum Group-based Cryptography
Orateur : 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[…] -
The influence of flicker noise on ring oscillator-based TRNGs
Orateur : 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
Orateur : 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.[…]-

Polytopes in the Fiat-Shamir with Aborts Paradigm
Orateur : Hugo Beguinet - ENS Paris / Thales
The Fiat-Shamir with Aborts paradigm (FSwA) uses rejection sampling to remove a secret’s dependency on a given source distribution. Recent results revealed that unlike the uniform distribution in the hypercube, both the continuous Gaussian and the uniform distribution within the hypersphere minimise the rejection rate and the size of the proof of knowledge. However, in practice both these[…]-

TrustSoC : a heterogeneous secure-by-design SoC architecture
Orateur : Raphaële Milan - Université Jean Monnet Saint-Etienne, CNRS, Laboratoire Hubert Curien UMR 5516
Since the 1970s, the complexity of systems on a chip has grown significantly. In order to improve system performance, manufacturers are integrating an increasing number of heterogeneous components on a single silicon chip. The incorporation of these components renders SoCs highly versatile yet significantly complex. Their multipurpose nature makes them suitable for use in a variety of domains,[…]-

FeFET based Logic-in-Memory design, methodologies, tools and open challenges
Orateur : Cédric Marchand - University of Lyon - Lyon Institute of Nanotechnology (UMR CNRS 5270)
Data-centric applications such as artificial intelligence and the Internet of Things (IoT) impose increasingly stringent demands on the performance, the security and the energy efficiency of modern computing architectures. Traditional approaches are often unable to keep pace with these requirements making necessary to explore innovative paradigms such as in-memory computing. This paradigm is[…]-
