POSTER: computer news || A NEW METHOD OF QUANTUM ENCRYPTION OVER FIBER OPTIC NETWORKS |

Employees of the Research Laboratory of Cambridge together with experts from Toshiba Corporation have developed a new way to protect quantum information transmitted over the Internet . The principle of quantum cryptography is based on the bit-wise information coding digital key from a single photon. If a hacker intercepts the photon, it inevitably violates coding that immediately detects an intruder. Previously, such an encoding required to send photons through a separate layer of optical fibers, which required additional lines of communication (probably military and government networks today use such methods of protection).  The results of a joint study of Cambridge and Toshiba - their importance lies in the fact that they allow to send a signal through encrypting common fiber optic cable, without the need to expand infrastructure. Needless ciphering equipment, according to Toshiba, will be relatively inexpensive, and certainly this development will become popular in the e-money circulation and exchange of private or corporate information.
