Séminaire ETIS-CELL – Pascal Cotret

Orateur : Pascal Cotret (ENSTA Brest)

Title: Contributions to software-hardware border security

Abstract:

This seminar provides an overview of some research activities, which examines security at various levels in both software and hardware. First, I will discuss work in which hardware supports software security (code monitoring on ARM, securing JIT compiled code). In the second part, the contributions presented involve hardware accelerators for security challenges: here, there is a strong algorithm-architecture fit to optimize the use of the FPGA resources to solve security problems. Finally, in the last section, we will focus on security at the microarchitecture level of embedded systems, and more specifically on cache memories in the context of using a TEE (Trusted Execution Environment) on a RISC-V processor.

Short bio: Pascal Cotret is an associate professor at ENSTA on the Brest campus. He earned his Ph.D. from the University of South Brittany in 2012, served as a lecturer and researcher at CentraleSupélec Rennes from 2014 to 2017, and then worked for two years at Thales SIX GTS before joining ENSTA in 2019. His expertise focuses on security at the software/hardware interface and embedded systems (heterogeneous architectures, reconfigurable components such as FPGAs). He is also interested in the algorithm-architecture matching of security mechanisms.
