British researchers say they are close to producing an off-the-shelf system that exploits quantum physics to create a secure communications channel.
Walter Simmons, a physicist at the University of Hawaii, together with his colleague, Professor Sandip Pakvasa, have come up with a clever scheme that would allow interstellar broadcasters to keep the coordinates of their home planet secret by taking advantage of advances in quantum cryptography.
The U.S. military will likely use the potential Iraq conflict to test out their information warfare training. They'll use this whole thing as a big training ground," according to James Bamford. "They'll experiment with everything they've been thinking about for a long time."
Quantum encryption is about to make life much more difficult for Internet spies. Not only will it make data uncrackable, the new technology also speeds up the increasingly slow process of sending coded messages over the Internet.
Scientists at Northwestern University say they have harnessed the properties of light to encrypt information into code that can be cracked only one way: by breaking the physical laws of nature.
An Indian scientist has devised a new way to determine with complete certainty whether a given number is prime, a breakthrough that could obsolete existing internet cryptography protocols.
Quantum cryptography keys encoded in photons of light have been transmitted more than 23 kilometres through air, British researchers have announced. They say the breakthrough is an important step towards a global communications system that is completely secure.
Until recently, the idea of quantum key distribution has been tested only in the physics laboratory. Now, a team from the University of Geneva and Swiss electronics company id Quantique have demonstrated what is described as the "first fully integrated quantum cryptography prototype machine" across a telecommunications network.
Researchers have developed an email protocol that allows senders to destroy messages either remotely or automatically, without a recipient's consent or cooperation.
Barak Jolish argues that it is impossible for the U.S. to stop terrorists from using advanced encryption technologies and attempting to do so would sap U.S. economic strength.
