'Unbreakable' Code to Stop Hackers

Question

Hum    6,934

SYDNEY, Australia (Reuters) -- Australian scientists believe they have developed an unbreakable information code to stop hackers, using a diamond, a kitchen microwave oven and an optical fiber.

Researchers at Melbourne University used the microwave to "fuse" a tiny diamond, just 1/1000th of a millimeter, onto an optical fiber, which could be used to create a single photon beam of light which they say cannot be hacked.

Photons are the smallest known particles of light.

Until now, scientists could not produce a single-photon beam, thereby narrowing down the stream of light used to transmit information.

"When it comes to cryptology, it's not so much of a problem to have a coded message intercepted, the problem is getting the key (to decode it)," said university research fellow James Rabeau, who developed the diamond device.

"The single-photon beam makes for an unstealable key."

The security of information depends on the properties of light that are used to transmit data.

Laser beams which are used at the moment send billions of photons, making it easy for hackers to steal some of them and break the code, said Rabeau.

The diamond device sends a stream of single photons, so that if the chain of communication is broken, the information becomes corrupted and a hacker immediately exposed to both the sender and the receiver, he said.

Only diamonds are known to create stable single-photon beams at room temperature.

Yes - but the data speed is slow at the moment, and the costs prohibitively expensive.

encryption couldn't be hacked either :rolleyes:

If theres a will, theres a way.

sooner or later, it probably can/will be broken.

Awesome extrememly interesting news and found right here in the best ****in' country in the world, and also the only place where Christ could never have been born, as in Australia, you cannot find 3 wisemen and a virgin.

But yeh its only a matter of time for this to be cracked

Was just about to say that... It's not if it can be broken, it's how long will it take to be broken..

is there any way to re-route the photon beam using a mirroring device to copy and re-send the same beam? if a similar device is constructed, they could intercept and rebroadcast the beam right? i have no idea what the friggin purpose of this photon crap is for anyways
