Users Pay Twice: The Hidden Energy Cost of Web Advertising
Speaker : Samuel Pélissier - CentraleSupélec
Advertisements are everywhere on the Web: search engines promote results, most websites display ads, some require users to accept ads as a condition for access, video streaming services fund their infrastructure through an increasing volume of ads, and much of the gaming industry has adopted ad-based revenue models. In exchange for free access to a wide range of content, web users sacrifice their[…]-

Post-Quantum Signatures from Symmetric-Key-Friendly Techniques: From MPC-in-the-Head to VOLE-in-the-Head
Speaker : Dung Bui - Northwestern University
The MPC-in-the-Head (MPCitH) paradigm turns a secure multiparty computation protocol into a zero-knowledge proof and, via Fiat–Shamir, into a signature scheme whose security relies only on symmetric-key primitives. The framework of Katz, Kolesnikov and Wang (KKW, CCS18), which moves most of the MPC work into a committed preprocessing phase that the verifier checks by opening all-but-one of the[…] -

Overcoming Challenges in Advanced Application Processor Attacks Using PEM-Assisted LFI
Speaker : Jean-Max Dutertre - Ecole Mines Saint Etienne
Modern Application Processors (or SoC) are complex multi-cores devices that run application code through an operating system. Manufactured using advanced FinFET technology, they may feature billions of transistors. They also operate at clock frequencies of over 1 GHz. This complexity is often presented as a barrier against fault injection attacks. Indeed, a potential attacker, would face two main[…]-

An Assessment of the Security of Reconfigurable Cloud Computing
Speaker : Russell Tessier - University of Massachusetts
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[…]-

Chiffrement homomorphe à l'aide des groupes après Nuida
Speaker : Pierre Guillot - Ravel Technologies/Université de strasbourg
Nuida et d'autres ont montré comment on peut obtenir un protocole de chiffrement pleinement homomorphe si l'on sait chiffrer les éléments d'un groupe G convenable, tout en sachant faire l'opération de G "en homomorphe". Les exemples étaient jusqu'à présent limités au chiffrement d'un bit à la fois, avec beaucoup d'opérations à effectuer pour "simuler" les portes logiques usuelles. Je vais[…]-
