  Users Pay Twice: The Hidden Energy Cost of Web Advertising

  • 04 décembre 2026 (11:00 - 12:00)

  • Inria Center of the University of Rennes - Room Petri/Turing

  Orateur : 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

  • 04 décembre 2026 (13:45 - 14:45)

  • IRMAR - Université de Rennes - Campus Beaulieu Bat. 22, RDC, Rennes - Amphi Lebesgue

  Orateur : 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[…]

  Post-quantum day of the cryptography seminar

  • 20 novembre 2026 (09:30 - 15:15)

  • Amphithéâtre E - Bâtiment 02A, Campus de Beaulieu - A map of the Beaulieu campus can be viewed at: https://www.univ-rennes.fr/en/beaulieu-campus-map (the building is south of the campus)

  A scientific day devoted to post-quantum cryptography, held in the wake of the European Cyber Week, with talks more technical than those presented at the ECW. The talks will take place at Amphi E in building 02A. To register for lunch, please do so before oct 30th using this link.

  Overcoming Challenges in Advanced Application Processor Attacks Using PEM-Assisted LFI

  • 06 janvier 2027 (11:00 - 12:00)

  • Laboratoire Lab-STICC - CNRS, UMR 6285, Centre de Recherche Christiaan Huygens, Rue de Saint-Maudé, Lorient - Salle CR-204

  Orateur : 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

  • 06 janvier 2027 (10:00 - 11:00)

  • Laboratoire Lab-STICC - CNRS, UMR 6285, Centre de Recherche Christiaan Huygens, Rue de Saint-Maudé, Lorient, - Salle CR-204

  Orateur : 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[…]
