Scientists Extract RSA Key From GnuPG Using Sound of CPU
kthreadd writes "In their research paper titled RSA Key Extraction via Low-Bandwidth Acoustic Cryptanalysis, Daniel Genkin, Adi Shamir and Eran Tromer et al. present a method for extracting decryption keys from the GnuPG security suite using an interesting side-channel attack. By analysing the acoustic sound made by the CPU they were able to extract a 4096-bit RSA key in about an hour (PDF). A modern mobile phone placed next to the computer is sufficient to carry out the attack, but up to four meters have been successfully tested using specially designed microphones."
You're missing the point. Only a dumb chat bot would take his typo literally
Who took it literally? I think I was being very kind in pointing out the typo by using gentle sarcasm. Perhaps my saying that 50 mHz is "well below" human hearing instead of "practically fucking DC" confused you?
This is "news for nerds." Any self-respecting nerd that doesn't know the SI system of prefixes should just turn the computer off and go back to bed. Trying to insult the messenger for a failure to preview a posting and being NINE ORDERS OF MAGNITUDE WRONG is just pathetic.
