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

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."

This is amazing all with a dimond and a microwave. May be this will solve the problem. Do you think this can really stop hackers, i mean they cant even get rid of pop-up adds.

Seems like there would be a more high-tech way than a microwave, but whatever works, I guess.

The idea for a medium that would be altered by interception has been around for quite a few years. The difficulty has been finding a method that :
1.) works
2.) is viable in the real world.

Now that #1 has been met, it seems that #2 could be a problem. I would think that your entire network would have to consist of the fiber-optics to be effective. However, it certainly could be used to protect high-scecurity networks over a limited area.

they can also cook a pizza with a microwave while they are protecting their information at the same time.
j/k

Very innovative.

MacGuyver would be proud.
