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. &quot;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,&quot; said the study's lead author, Physics Professor Hoi-Kwong Lo. &quot;If an eavesdropper tries to intercept the transmission of the encryption key, he will give himself away by disturbing the photons. &quot;However, real-life light sources occasionally send out more than one photon and an eavesdropper can steal the additional pulse without the sender knowing.&quot; Lo's technique creates different signals of various intensities that act as decoys to distract the eavesdropper from the secret message.&quot;<br /> <br /> Everytime something new comes up people start making fuss about it.<br /> Let the time tell, to what extent it is going to protect.<br /> <br /> BTW : are we going to have Quantum IDA Pro soon :P??
