Breaking RSA Keys by Listening to Your Computer

Posted by Hemos on 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."

    No power saving for me! My encrypted porn is far too important.

    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
