This weekend, while sulking over my lack of forward progress in smartcard power analysis, I added WiFi control to a Bash Bunny I’ve got lying around. Somehow, Google turns up nothing on the topic (surely I’m not the only person … Continue reading →
Trace Alignment!
Over the past week, I have progressed my work in power analysis of smartcards. By replacing my original power shunt (1.5R) with a higher resistance (4.7R) alternative, I’m now able to retrieve significantly higher resolution power traces, even at 1.8V. … Continue reading →
