Project Snapshot
Fault Injection Attacks (FIA) present considerable threats to the security and reliability of embedded systems. FIAs can compromise an embedded processor by altering its clock signal, power supply or by using electromagnetic pulses. This study focuses on analyzing the impact of FIA on the Physical Memory Protection (PMP) configuration flow within a CVA6 RISC-V core. We conducted fault injection campaigns on an FPGA implementation using an ARTY A7-100T board to characterize the resulting fault effects. To achieve this, we utilized clock glitches as the primary method of fault injection. Our experimental findings reveal that FIAs can induce various effects on PMP configuration registers. By categorizing these effects according to the injection parameters, we demonstrate that specific effects can be reliably achieved under varying injection conditions, often with a high probability of success for an attacker.

Kévin QUENEHERVE
PHD Student in Electrical and Computer Engineering at Université Bretagne Sud (UBS) – Lab-STICC (UMR CNRS 6285) in France
Kevin Queneherve is a PhD student in the ARCAD team of Lab-STICC laboratory (UMR CNRS 6285) at Université Bretagne Sud (UBS), Lorient, France. After obtaining a master’s degree in CyberSecurity of Embedded Systems in UBS, he completed an end-of-study internship within the ARCAD team on the performance and security analysis of the memory isolation mechanism of RISC-V cores for embedded systems. His current research work focuses on the study and design of an embedded processor robust against fault-injection attacks.
