“FaceWhisperer: USB host add-on for the ChipWhisperer side-channel analysis tool.
FaceWhisperer is a hardware add-on for the ChipWhisperer side-channel analysis tool, for working with devices that primarily communicate over USB. The goal is to create a USB host controller scripted with an experiment, all running totally synchronous with the target. This should give predictable timing each time the experiment is run from a target reset.
