RSA Key Extraction via Low-Bandwidth Acoustic Cryptanalysis

[Doug Gentges]

It turns out that you can gain information about the instructions being
executed in a CPU by listening to the ultrasonic noises made by the power
regulator.  The authors use this information to devise a known plaintext
key recovery attack against RSA
