Bridging Deep Learning and Classical Profiled Side-Channel Attacks
Orateur : Gabriel Zaid
Over the recent years, the cryptanalysis community leveraged the potential of research on Deep Learning to enhance attacks. In particular, several studies have recently highlighted the benefits of Deep Learning based Side-Channel Attacks (DLSCA) to target real-world cryptographic implementations. While this new research area on applied cryptography provides impressive result to recover a secret[…] -

Lattice-based NIST candidates: abstractions and ninja tricks
Orateur : Thomas Prest
I will present the remaining lattice-based candidates for standardization by NIST (2 signature schemes, 5 encryption schemes). At a high level, these can all be interpreted as straightforward instantiations of decades-old paradigms. But when we look under the hood, all of them make design choices which impact their security, efficiency and portability in distinct manners; we will discuss these.[…] -

Security of Hardware/Software Interfaces : Research Chair of the Cybersecurity Research Cluster
Orateur : Guillaume Hiet
We proposed to host a thematic semester on attacks based on the interaction between software and hardware. The goal would be to host one workshop, one summer school for young researchers, as well as multiple seminars and longer stays for researchers, spanning September 2019 to March or April 2020. This thematic semester will be funded by the DGA in the context of the Cybersecurity Research Cluster[…] -

When Electromagnetic Signals Reveal Obfuscated Malware: Deep and Machine Learning Use cases
Orateur : Duy-Phuc Pham et Damien Marion
The Internet of Things (IoT) is constituted of devices that are expo-nentially growing in number and in complexity. They use plentiful customized firmware and hardware, ignoring potential security issues, which make them a perfect victim for cybercriminals, especially malware authors.We will describe a new usage of side channel information to identify threats that are targeting the device. Using[…] -

TRAITOR : a multi clock-glitch attack platform reproducing EMI effects at low-cost
Orateur : 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[…] -

Laser-Based Attacks Against FPGA Bitstream Encryption
Orateur : Heiko Lohrke
Field programmable gate arrays (FPGAs) use encryption to protect the configuration data or “bitstream” containing the design to be run on the device. This encryption aims at protecting the intellectual property and other secrets contained in the bitstream and preventing e.g. cloning or tampering with an FPGA implementation.This talk will demonstrate how attackers can use failure analysis equipment[…] -
