Abstract:
We propose a three-dimensional quantum noise stream cipher (3D-QNSC) that newly uses time-domain masking as well as amplitude and phase QAM encryption. We demonstrate a real-time 560 km transmission using FPGA-based transmitter/receiver and successfully obtain BER of 0.5 for all-bits of 3D-QNSC signal against eavesdropper.
