Breaking RSA Keys by Listening to Your Computer 186

Posted by Hemos on Saturday May 08, 2004 @12:06PM from the sssh-i'm-hunting-for-wabbits dept.

An anonymous reader writes "Adi Shamir and crew gave a talk on preliminary results in extracting a private RSA key just by listening to the computer!. Similar to power analysis and LED leakage, this is a non-invasive, side channel attack that may have applications to tamper-resistant systems. It appears to be related to noisy capacitors on the motherboard, an effect which has been observed when CPU power saving is enabled on laptops."

I've got so many fans running in my computer that you can't even hold a conversation in the same room, much less listen for capacitors

i've got the wonderful feature of sound effects from my box when performing just about any GUI operation you care to mention, i originally thought that it was a monitor issue, now you tell me my privacy is at risk because of it!

time to fit more fans and drown out the noise.

So, in all, this paper is not insignificant, but it's also not a reason to completely give up on security or to install a cone of silence around your computer.

I'm not sure that I could fit this [cinerhama.com] around a computer in the first place.

It tells me to troll Slashdot, and buy Kenny G albums.

I'm starting to think it doesn't have my best interests at heart...
