According to this article, 4096-bit RSA is crackable by listening to the sound of the voltage regulator.

I haven't read the research paper yet, but it does make sense. A switching regulator would change frequency to compensate for voltage drop.
 
How about: don't put computers handling sensitive data anywhere where their circuitry and be recorded by spies?

Physical security > logical security
 
We have noise generators.. it's called an OS just do anything else when the encryption's going on and it'll be likeyl drowned in other computer activity...
 
Actually the paper summary mentions that multitasking is not a problem. It is required to be able to feed the decryption engine lots of specially crafted messages, though. This is usually not possible on a private computer unless you specifically activate some automation.
