[Sks-devel] [OT] RSA Key Extraction via Low-Bandwidth Acoustic Cryptanalysis

[Filip Stefaniak]

Hi,
however this is not about SKS, but may be interesting to you.

RSA Key Extraction via Low-Bandwidth Acoustic Cryptanalysis

"... Here, we describe a new acoustic cryptanalysis key extraction
attack, applicable to GnuPG's current implementation of RSA. The attack
can extract full 4096-bit RSA decryption keys from laptop computers (of
various models), within an hour, using the sound generated by the
computer during the decryption of some chosen ciphertexts. We
experimentally demonstrate that such attacks can be carried out, using
either a plain mobile phone placed next to the computer, or a more
sensitive microphone placed 4 meters away."
