Today i came across this article.
Quantum decoys foil code breakers ( http://www.whitedust.net/speaks/916/Quantum decoys foil code breakers/ )
Extract :
"Computer code-makers may soon be able to thwart code-breakers thanks to a new quantum cryptography method, University of Toronto scientists said Monday. Quantum cryptography uses particles of light to share secret encryption keys relayed through fiber-optic communications. A paper published in the June 16 issue of the Physical Review Letter detailed how varying the intensity of laser light particles (photons) used in fiber-optic communications can create decoys that catch eavesdropping attempts. "To exchange secret communication, the sender and the recipient first have to exchange a random series of 0s and 1s ... through a sequence of photons," said the study's lead author, Physics Professor Hoi-Kwong Lo. "If an eavesdropper tries to intercept the transmission of the encryption key, he will give himself away by disturbing the photons. "However, real-life light sources occasionally send out more than one photon and an eavesdropper can steal the additional pulse without the sender knowing." Lo's technique creates different signals of various intensities that act as decoys to distract the eavesdropper from the secret message."
Everytime something new comes up people start making fuss about it.
Let the time tell, to what extent it is going to protect.
BTW : are we going to have Quantum IDA Pro soon :P??
