Improved Blind Side-Channel Analysis by Exploitation of Joint Distributions of Leakages
Speaker : Léo Reynaud
Les attaques side channel classiques nécessitent généralement la connaissance du clair (ou du chiffré) afin de calculer des données internes qui seront comparées à des fuites. Des attaques permettent cependant de s’affranchir de ces connaissances, les attaques par distributions jointes. Ces attaques supposent un attaquant capable d’inverser le modèle de consommation, mais aucune connaissance sur[…] -
TRAITOR : a multi clock-glitch attack platform reproducing EMI effects at low-cost
Speaker : Ludovic Claudepierre
Electromagnetic injection (EMI) is a common and non-invasive technique used to perform fault attacks. In that case, an electromagnetic wave is radiated by an antenna in the close vicinity of the targeted microcontroller (STM32 in our case).The clock signal is generated thanks to a Phase-Locked-Loop (PLL). The PLL is highly sensitive to EMI and then induces severe disruption on the clock signal[…] -
True Random Number Generators enabled hardware security
Speaker : Bohan Yang
True randomness is all about unpredictability, which can neither be qualified nor quantified by examining statistics of a sequence of digits. Unpredictability is a property of random phenomena, which is measured in bits of information entropy. Application of randomness spans from art to numerical computing and system security. Random numbers enable various cryptographic algorithms, protocols and[…] -

Designing and deploying post-quantum cryptography
Speaker : Jean-Philippe Aumasson - Teserakt AG
I will review the hash-based signature submitted to the NIST competition jointly with Guillaume Endignoux, discussing its assurance level and performance. Then I will discuss the challenges of deploying post-quantum cryptography in an end-to-end encryption product for machine-to-machine communications.<br/> lien: http://desktop.visio.renater.fr/scopia?ID=721783***6864&autojoin -
Voting : You Can’t Have Privacy without Individual Verifiability
Speaker : Joseph Lallemand (Loria)
Electronic voting typically aims at two main security goals: vote privacy and verifiability. These two goals are often seen as antagonistic and some national agencies even impose a hierarchy between them: first privacy, and then verifiability as an additional feature. Verifiability typically includes individual verifiability (a voter can check that her ballot is counted); universal verifiability […]
