ECDSA Key Extraction from Mobile Devices [research]

ECDSA Key Extraction from Mobile Devices via Nonintrusive Physical Side Channels

Is it reproducible with CWLite for example?

It should be! The only issue would be w.r.t. sample length - the CW-Lite does short samples, and doesn’t yet have a “dump to USB” mode. As such you couldn’t capture long enough traces…

It’s actually something I plan on adding. It will be added first to our more advanced CW-Capture box (to be released this summer), as the FPGA resources in the CW-Lite are fairly limited, and I don’t know if it would fit alongside everything else.

Warm Regards,
