One Fault Can Go A Long Way
Speaker : Shivam Bhasin
*Abstract:* Fault attacks are considered among critical threat to embedded cryptography. This talk will be divided into in two parts. The first part of the talk will explore application of faults on advanced security primitives. We present persistent fault analysis introduced at CHES 2017 and its capability to bypass state of the art fault countermeasures as well as higher-order masking with one[…] -

Implémentations sécurisées et évaluation pré-silicium contre les attaques physiques.
Speaker : Sofiane Takarabt
Side-channel attacks remain a permanent threat against embedded systems, thus reliable protections should be implemented and must be minutely evaluated. In this presentation, we study different possible ways to evaluate against such threats. We show how an evaluation can be carried out to validate a security level of a protected hardware implementation. This approach allows us to estimate in[…] -

Schindler-Itoh/Wiemers revisited: recovering full RSA/ECC private key from noisy side-channel observations
Speaker : Victor Lomné et Thomas Roche
Side-channel attacks on public-key cryptography (i.e. modular exponentiation for RSA or scalar multiplication for ECC) often boils down to distinguishing the 0s from the 1s in the binary representation of the secret exponent (resp. secret scalar).When state-of-the-art countermeasures are implemented, this detection must be errorless: thanks to masking techniques, erroneous masked exponents (resp.[…] -

Rank metric cryptography and its implementations
Speaker : Nicolas Aragon
In 2017, the NIST (National Institute for Standards and Technology) started astandardization process in order to select post-quantum encryption and digital signature schemes. Among the proposed solutions, two rank-metric based encryption schemes were selected for the second round of the standardization process: ROLLOand RQC.This raised questions about both the performance and the security of the[…] -

Laser-Based Attacks Against FPGA Bitstream Encryption
Speaker : 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[…] -

Security of Hardware/Software Interfaces : Research Chair of the Cybersecurity Research Cluster
Speaker : 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[…] -
