University of Toronto professor Hoi-Kwong Lo says he can now use a photon of light to thwart the most sophisticated computer theft schemes that hackers can devise.
His proposal is like this: Using the infinitesimally small light particles it’s possible to confound even the most elaborate decoding plots and, eventually, safeguard financial or classified information from electronic spies or burglars.
Lo, whose study is to be published in the upcoming issue of the physics journal Physical Review Letters says;
We are using fundamental quantum mechanics principles that no eavesdropper can do anything about. We can use this to confuse the eavesdropper, and severely limit what he can do. The principle is that if someone makes some measurement, or has some interaction (with the protecting photon), then its quantum state will change.
This means that merely looking electronically at the photon keys will automatically change their shape and render them useless in unlocking the information they protect.
This theory has been out for sometime now, but then Lo says that it can be incorporated at the industrial level viably.
Anyway, let’s see what shape this takes place.
