Cracking RSA 4096-bit encryption with a microphone

(Phys.org) —A trio of researchers in Israel has discovered that it is possible to crack 4096-bit RSA encryption keys using a microphone to listen to high-pitch noises generated by internal computer components. Adi Shamir (co-inventor of RSA), Daniel Genkin and Eran Tromer have published a research paper describing the technique on a Tel Aviv University server.

I posted this 2 week ago and still think it's possible. If one could biggie back a high frequency on a low frequency I believe many things can be done. The low frequency will do the penetrate of a structure and then the high frequency will do its nasty work.

Lets not forget VLF and ULF (Very Low Frequency) (Ultra Low Frequency). They travel very far and trough most everything. I don't believe a computer can transmit such signals because of the power needed but might be able to receive them allowing a bug to be installed into a high risk secure system

That's an interesting thought. Remember reading ALOT about ULF a few years ago, something about Navy testing and the ill effects on whales if I remember right. Food for thought definitely.

Listen up: RSA keys snatched by recording CPU sounds with a phone

Quote:
It sounds too preposterous for even James Bond: by placing a mobile phone next to a PC, researchers can “listen” to the faintest sound a CPU makes as it churns away on RSA-encoded content and extract the keys themselves.

Preposterous, except for the fact that Adi Shamir, one of the co-developers of the RSA encryption algorithm, co-wrote the paper that describes how to do it. Daniel Genkin and Eran Tromer were the other two authors.

Just think what a laptop built in mic or speaker might be able to do.
This can get scary in a heart beat.

Thanks Bill.
