It is unlikely that this particular attack can be used against smart
cards. They are quite different from a general purpose PC. Modern
cards are designed to mitigate many classes of side-channel attacks
since cards started to be targeted more than 25 years ago.
The private keys are only on the card and not accessible from the PC.
Die Gedanken sind frei. Ausnahmen regelt ein Bundesgesetz.
