This study demonstrates the optical fiber transmission of the Y-00 quantum stream cipher with quantum deliberate signal randomization (QDSR). QDSR is a deliberate signal randomization driven by a quantum random number generator, which substantially enhances signal masking using quantum noise to realize higher security. A 10-Gb/s line-rate dualpolarization phase-shift keying Y-00 cipher with QDSR is transmitted over a 400-km field-installed single-mode fiber link with optical amplifiers. When the phase levels after encryption and the index of QDSR are set to 216 and 0.2, respectively, the quantum noise masking number increases by a factor of more than 40 compared to that without QDSR, which enhances security. However, the transmission penalty owing to QDSR remains small.
