Description
In this talk, we examine efforts to protect network processing and computation in cloud-based FPGAs from hardware- and software-based attacks. FPGAs have served as integral components in cloud computing for a decade, even though commercial FPGA architectures were not designed for cloud deployment. A range of potential attacks on cloud-based FPGAs and their remediations are examined. We quantitatively assess the likelihood of successful attacks under practical scenarios with a focus on most recent threats including voltage and crosstalk attacks, memory attacks, and data extraction attacks. After attack analysis, we examine creative hardware and software techniques that make cloud-based FPGA attacks less likely. These remediations include architectural, sensor-based, and software monitoring-based approaches. We conclude the talk with a look forward, as FPGAs serve an increasingly important role in cloud network processing and computation.

Using High Level Profiling Data to Early Assess the Fault Tolerance of Complex Digital Components
Orateur : Luc NOIZETTE - Nuclétudes (filiale Ariane group)
This presentation outlines an innovative methodology for estimating the fault tolerance of complex components based on application profiling obtained using a high-level virtual platform. A derating factor, derived exclusively from profiling metrics (e.g., lifetime in memory and registers), is calibrated using a reliability dataset collected from a set of benchmarks. Applying it to test softwares[…]-

Securing processor's microarchitecture against SCA in a post-quantum cryptography setting
Orateur : Vincent MIGLIORE - LAAS-CNRS
Hardware microarchitecture is a well-known source of side-channel leakages, providing a notable security reduction of standard cryptographic algorithms (e.g. AES) if not properly addressed by software or hardware. In this talk, we present new design approaches to harden processor's microarchitecture against power-based side-channel attacks, relying on configurable and cascadable building blocks[…]-

Compositional Semantics for Detection and Defense of Speculative Leaks
Orateur : Xaver Fabian - CISPA Helmholtz Center for Information Security
Speculative execution improves CPU performance but introduces vulnerabilities, known as Spectre attacks, which exploit microarchitectural side effects to leak sensitive data. Modern processors employ multiple interacting speculation mechanisms, yet existing approaches predominantly analyze them in isolation, which limits both the automated detection of complex leaks and the formal verification of[…]-
