Abstract

We propose coarse-to-fine phase modulation for Y-00 quantum stream cipher that employs extremely high-order PSK modulation for signal masking by quantum noise. Encryption with a record-high 217phase levels and penalty-less digital-coherent decryption are demonstrated at 10 Gbaud.

Digital-coherent PSK Y-00 quantum stream cipher for secure fiber-optic transmission

Ken Tanizawa, Fumio Futami

We present a symmetric-key direct data encryption technique utilizing signal masking by quantum noise, called Y-00 quantum stream cipher. Physical encryption of phase-shift-keying (PSK) Y-00 quantum stream cipher is achieved by our proposed extremely high-order phase modulation. Two cascaded phase modulators are driven with two synchronized digital-to-analog converters for coarse-to-fine modulations, resulting in a record 217 phase levels for the quantum noise masking. Decryption of the cipher is implemented in digital signal processing after intra-dyne coherent detection with a free-running local oscillator. We experimentally demonstrate transmission of 10-Gbaud digital-coherent PSK Y-00 cipher with 217 levels over a 240-km field-installed single-mode fiber.

Ken Tanizawa, Fumio Futami

For secure fiber-optic transmission, we demonstrate a 10-Gbaud Y-00 quantum stream cipher that achieves quantum noise masking using 214(=16,384) intensity-level modulation. Coarse-to-fine driving of a dual-drive Mach-Zehnder modulator using two synchronized digital-to-analog converters is employed for the modulation. Successful off-line decryption of the cipher is achieved.

Experimental demonstration of PSK Y-00 quantum noise randomized stream cipher based on cascaded multiple phase modulators

A 100-km fiber transmission with 10 Gbit/s is demonstrated based on Y-00 quantum noise randomized stream cipher (QNRC) utilizing cascaded phase shift keying (PSK). The proposed of the experimental scheme is to break the limitation of high-resolution and high-speed digital-to-analog converter (DAC) in the QNRC systems. In this paper, a 10 Gbit/s encrypted signal generated by employing seven cascaded phase modulators (PM) which are driven by designed electrical voltage signals at the transmitter side. The encrypted signal is successfully decrypted by the same six cascaded PMs and digital coherent detection. The experimental results show that the power penalties between back to back (B2B) and 50 km transmission and between B2B and 100 km transmission are 1.2 dB and 2 dB, respectively. The proposed PSK-QNRC system can realize error-free transmission. Meanwhile, the bit error rate (BER) performance of the proposed scheme is well below the forward error correction (FEC) threshold. However, the DAC sampling rate of the traditional scheme is not enough to recover the complete waveform. This proposed scheme greatly improves the security of the system.
