RSA Key Extraction via Low-Bandwidth Acoustic Cryptanalysis
Playing loud music when encrypting/decrypting/typing in your password will defend against acoustic attacks, right?This other type of attack, however, isn't so easily guarded against:Beyond acoustics, we demonstrate that a similar low-bandwidth attack can be performed by measuring the electric potential of a computer chassis. A suitably-equipped attacker need merely touch the target computer with his bare hand, or get the required leakage information from the ground wires at the remote end of VGA, USB or Ethernet cables.This serves as a reminder that it's pretty much impossible to defend against an attacker that has physical access to your box.
