Fault Injection II: Does glitch width really matter?
When performing fault injection attacks we are used to see how the glitch width moves within a set of values, hoping this would help hit the right combination. This is true while blindly searching for a new vulnerability. But when it comes to repeatability, does it really matter? Building upon our previous post on fault…

Fault Injection I: Crowbar Circuit vs Analog CMOS Switch
As part of my ongoing research into fault injection techniques, my current goal is to understand and successfully use fault injection in a target SoC with minimal modification to the board, which would reduce the entry barrier for performing an attack and minimize potential damage to the target board. I chose the well-known nRF52 family,…
