Pre-silicon security analysis of RISC-V processors to fault injection attacks – CEA

This talk proposal showcases the sensitivity of processor microarchitectures to fault injection attacks, which threat hardware and software security. As a consequence, security analysis must take into account both the hardware and software models of system under analysis. Furthermore, fault injection requires to consider exhaustively all the possible injection locations, resulting in unprecedented complexity. We present our methodology and two tools developed for this purpose. In particular, our approach has enabled us to identify a new vulnerability in the OpenTitan secure core.
