Australian Gov't May Employ a Homegrown Quantum Key System

mask.of.sanity writes "The Australian government is trialling a new Quantum Key Distribution (QKD) system built by Aussie scientists. QKD is considered the world's toughest security because the slightest attempt to intercept the one time keys, coded into lasers at the quantum level, will disrupt the beam. The technology differs from current cryptography tech primarily because it's cheap. Well, less than the $US100k price tag of rival systems. It uses off-the-shelf networking gear instead of proprietary technology, and is built on open standards, so it's easier to install. The random key is encoded at the quantum level in the sidebeam in the phase and amplitude, or brightness and colour, of a highly tuned laser beam. The creators, who built the system in part for their Ph.Ds, said it can be used to transport the most sensitive data like critical infrastructure and secret commercial IP. The days of hand-delivered security keys are numbered."

Quantum Key + Internet Filter?

[Narnie]

So... are the scientists that frustrated with the Aussie internet filter that they're employing a quantum key encryption system just so they can get their porn?

I hear that the technology is called "Key Order Assignment by Laser Application".

No, from what I understand the system involves strapping a key to a shark who'll swim it to the recipient. The friggin' laser shoots anyone trying to intercept it, thereby guaranteeing security.

Sharks with friggin laser beams have become more adundant as of late, which is why they can do this so cheaply.
