Abstract
A METHOD FOR USE IN QUANTUM CRYPTOGRAPHY SYSTEM, PARTICULARLY FOR ENHANCING THE SECURITY LEVEL OF OBTAINING THE CRYPTOGRAPHIC KEY TO ENCODE THE INFORMATION COMMUNICATED BETWEEN TO LEGITIMATE PARTIES. A PLURALITY OF REFERENCE SIGNALS (RS) WITH DIFFERENT FREQUENCIES AND AMPLITUDES ARE TRANSMITTED BY ALICE TO BOB, FOLLOWED BY TRANSMITTING A PLURALITY OF QUANTUM SIGNALS (QS) WITH DIFFERENT INTERVAL TIMES AND AMPLITUDES. BOB MEASURES THE ARRIVAL TIME OF THE REFERENCE SIGNALS (RS) AND QUANTUM SIGNALS (QS) AT HIS END, AND REPORTS TO ALICE. ALICE PROVIDES THE ACCURATE ARRIVAL TIMES AND BOB DISCARDS THE ERRONEOUS ONES. BASED ON THE PREFERRED EMBODIMENTS OF THE PRESENT INVENTION, THE KEY IS OBTAINED BY WAY OF MEASURING THE ARRIVAL TIMES OF REFERENCE SIGNALS (RS) AND QUANTUM SIGNALS (QS).
