EM-Fault It Yourself: Building a Replicable EMFI Setup for Desktop and Server Hardware

Niclas Kühnapfel, Robert Buhren, Hans Niklas Jacob +3

EMFI has become a popular fault injection (FI) technique due to its ability to inject faults precisely considering timing and location. Recently, ARM, RISC-V, and even x86 processi…

Automatic Extraction of Secrets from the Transistor Jungle using Laser-Assisted Side-Channel Attacks

Thilo Krachenfels, Tuba Kiyan, Shahin Tajik +1

The security of modern electronic devices relies on secret keys stored on secure hardware modules as the root-of-trust (RoT). Extracting those keys would break the security of the…
