Acoustic sie channel attack

[David Picon Alvarez]

Hi,

Maybe you've already seen this link:

It seems that it is possible to extract some information from the noise of
the processor when doing public key work, and potentially do timing attack.

I'm not sure this is a particularly dangerous side channel, anyway, but just
in case you're interested.
