Acoustic Cryptanalysis: Extracting RSA Key From GnuPG by capturing Computer Sound

‘RSA Key Extraction via Low-Bandwidth Acoustic Cryptanalysis’, is an interesting paper recently published by Three Israeli Security Researchers at Tel Aviv University.

They claimed that, they have successfully broken one of the most secure encryption algorithms, 4096-bit RSA, just by capturing Computer’s CPU Sound while it runs decryption routines.
