3.6.4 Extraction of 4096-Bit RSA Keys Using Microphone
The authoritative cryptographer Adi Shamir (letter S in RSA), mentioned in this
work for many times, in cooperation with his colleagues published a new scientific
work called “RSA Key Extraction via Low-Bandwidth Acoustic Cryptanalysis” [23].
This complex name denotes an extremely accessible method of extraction of RSA
keys (in the GnuPG) implementation with the help of a regular mobile phone or
a microphone. It only takes putting the phone within the range of 30 cm around
the victim’s computer; using high-quality microphones can increase the distance of
extraction of keys to 4 m.
It may be hard to believe; however, at the moment of publication of this book,
many successful experiments to extract keys from various models of computers have
