Scientists at Tel Aviv University have developed a digital security tool with existing fiber optic and computer technology that transmits binary lock-and-key information in the form of light pulses. The device, invented by Dr. Jacob Scheuer, TAU's School of Electrical Engineering, allegedly ensures that a shared key code can be unlocked by the sender and receiver, and absolutely nobody else. Dr. Scheuer explained: "Rather than developing the lock or the key, we've developed a system which acts as a type of key bearer." The researchers continued: "The trick is for those at either end of the fibre optic link to send different laser signals they can distinguish between, but which look identical to an eavesdropper." Dr. Scheuer added: "We've already published the theoretical idea and now have developed a preliminary demonstration in my lab. Once both parties have the key they need, they could send information without any chance of detection. We were able to demonstrate that, if it's done right, the system could be absolutely secure. Even with a quantum computer of the future, a hacker couldn't decipher the key." The findings were due to be presented at the next laser and electro-optics conference at the Conference for Lasers and Electro-Optics (CLEO) in San Jose, California. ANI / yahoo news
