Perfect secrecy has come a step closer with the launch of the world’s first computer network protected by unbreakable quantum encryption at a scientific conference in Vienna.

The network connects six locations across Vienna and in the nearby town of St Poelten, using 200 km of standard commercial fibre optic cables.

Quantum cryptography is completely different from the kinds of security schemes used on computer networks today.

These are typically based on complex mathematical procedures which are extremely hard for outsiders to crack but not impossible given sufficient computing resources or time.

But quantum systems use the laws of quantum theory, which have been shown to be inherently unbreakable.

The basic idea of quantum cryptography was worked out 25 years ago by Charles Bennett of IBM and Gilles Brassard of Montreal University, who was in Vienna to see the network in action.

“All quantum security schemes are based on the Heisenberg Uncertainty Principle, on the fact that you cannot measure quantum information without disturbing it,” he explained.

“Because of that, one can have a communications channel between two users on which it’s impossible to eavesdrop without creating a disturbance. An eavesdropper would create a mark on it. That was the key idea.”

Wow … people have been discussing this possibility for a long time, but apparently the zeitgeist has come to fruition.

Following in the wake of Februarys news that customs agents were seizing electronics and making copies of all the files on cell phones and laptop hard drives, a federal appeals court has ruled on the legality of such searches. The result: Yeah, customs can do whatever it wants to your computer when you come across the border, without a warrant, and without cause.

The ruling extends to all electronics: In addition to laptops, feds can seize phone records and even digital pictures on your camera as they hunt for evidence. The ruling was unanimous among the three appellate judges.

Be assured that the ruling has little to do with thwarting terrorism. The appeal was actually part of an ongoing trial of a man named Michael Arnold, who returned from the Philippines and had his laptop scoured by the feds. They found purported images of child pornography on the laptop and later arrested him. In his trial, the evidence was suppressed for probable cause issues, as the court said that customs had no reasonable suspicion to search his laptop in the first place. That ruling has now been overturned.

As Wired notes, the court did not rule on whether you have to help agents access your hard drive. If you use a password or encryption, the court was mum on whether you can be compelled to provide information on bypassing that security in order to access materials on the drive.

I recommend sticking a thumb(drive) up your ass
