ResearchResearch Projects

  • Labex CominLabs SCRATCHS (2021-2024)
  • The goal of the SCRATCHS project is to co-design a RISC-V processor and a compiler toolchain to ensure by construction that a security sensitive code is immune to timing side-channel attacks while running at maximal speed

  • Labex CominLabs HardBlare (2015-2019)
  • The general context of the HardBlare project is to address hardware-assisted Dynamic Information Flow Control (DIFC) that generally consists in attaching marks to denote the type of information that are saved or generated within the system. These marks are then propagated when the system evolves and information flow control is performed in order to guarantee a safe execution and storage within the system.

  • ANR TSUNAMY (2013-2017)
  • The TSUNAMY project addresses the problem of secure handling of personal data and privacy in manycore architectures. The TSUNAMY project aims to propose a solution of trust building to execute many independent applications in parallel, safely and ensuring respect for the privacy of users.

  • PEPS SISC INS2I "HomCrypt" (2017)
  • Prototyping of a Hardware/Sofware design for homomophic encryption
