Diamonds could well be the next big thing that protects the digital home.
Australian scientists have revealed that by inserting a diamond into a fibre optic cable that can take the sparkle out of hacking.
Scientists in Melbourne believe they have developed an unbreakable information code that stops hackers reaching devices inside a digital home. By integrating a diamond inside an optical cable they have proved that a device cannot be hacked.
During tests the researchers at Melbourne University used a microwave to “fuse” a tiny diamond, just 1/1000th of a millimetre, onto an optical fibre, 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 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 … instead of … Only diamonds are known to create single-photon beams.
Rabeau and his team have received an A$3.3 million innovation grant from the Victoria state government to develop a prototype and commercialise the technology.
