bit ECDSA key from a smart card by analyzing video footage of
the power LED of a smart card reader via a hijacked Internet-connected security camera located 16 meters away from the smart
card reader, and (2) a 378-bit SIKE key from a Samsung Galaxy
S8 by analyzing video footage of the power LED of Logitech Z120
USB speakers that were connected to the same USB hub (that
was used to charge the Galaxy S8) via an iPhone 13 Pro Max." To all the EEs out there. PSRR and power supply cross talk is a thing... |
