Eavesdropping on the CPU

People are creative.
There are people who came up with the idea of listening and deciphering the sound of people typing.

And then there are people who came up with the idea of tuning in a EM receiver to the frequency emanated by the CPU.

Sort of like a transistor radio that can "play" the data processing going on in your CPU !
There have been people tuning into other EM transmissions, but this appears to be the first attempt at listening to the CPU.

Using this technique, they claim to be able to distinguish the CPU operations down to the last assembly code instruction !!! Shocked
They claim that each instruction has a characteristic signature sound and by sampling these sounds, they can generate a log of the entire processing that goes on in the CPU.

The primary use ? Breaking encryptions. Twisted Evil
