It's the most "current" news you'll read all day: The pattern of the electric currents that pass through your laptop computer can be used to determine your encryption keys, as a group of three Israeli researchers at Tel Aviv University have shown. By measuring the electric potential running through a laptop's casing, or through a cable attached to the machine, or even by measuring the electric potential of a human touching the casing, the researchers were able to extract two different types of encryption keys used in the open-source encryption hardware known as GnuPG. When the computer's owner accessed GnuPG software and entered the decryption key, the pattern of electrical potential that flows through the laptop's metal parts was enough to let the researchers determine 4096-bit RSA keys and 3072-bit ElGamal encryption keys.
