When Keyboards Talk, Who Listens?

We already knew that computers and electronic devices generate behaviors that could be picked up at a distance; this is the stuff of spy novels and movies. The TEMPEST program, rumored to have started as far back as the early to mid 1960s (src: http://cryptome.org/tempest-time.htm), provided specific guidance on shielding electronic devices to prevent eavesdropping.

Now two researchers in Switzerland have actually gotten it to work in a way that can be easily demonstrated: what you type on a WIRED keyboard can be picked up and decoded from the same room and from an adjacent room. Watch the videos to get the full effect - http://lasecwww.epfl.ch/keyboard/ - Be scared, be very scared.
