Using side-channel technology, researchers at Tel Aviv University can extract decryption keys from RSA and ElGamal implementations without altering or having control of a computer.

Not that long ago, grabbing information from air-gapped computers required sophisticated equipment. In my TechRepublic column Air-gapped computers are no longer secure, researchers at Georgia Institute of Technology explain how simple it is to capture keystrokes from a computer just using spurious electromagnetic side-channel emissions emanating from the computer under attack.
