Abstract

We demonstrate stealthy and encrypted IM/DD PAM-4 transmission where the signal is buried under ASE noise and coded with spectral phase mask. We report a considerable SNR gain which leads to error-free transmission despite negative OSNR.

Demonstration of coherent stealthy and encrypted transmission for data center interconnection

We show in an experiment a covert transmission of QPSK and 64-QAM over up to 100km of SSMF, digitally encrypted with spectral phase mask, buried under ASE noise with negative -15 dB/0.1nm OSNR. We record a post-FEC error free BER for a stealthy channel, at 16 Gbps on a single polarization.

Demonstration of Stealthy and Encrypted Optical Transmission Below Adjacent 50 GHz DWDM Channels

Eyal Wohlgemuth, Yaron Yoffe, Pantea Nadimi Goki +4 more

A stealthy and encrypted transmission is demonstrated in a dense-WDM network. The residual gap between two neighboring commercial channels is utilized for the transmission of the secured channel, hidden below the amplifier noise at negative -10 dB/0.1nm OSNR. The stealthy and encrypted channel is generated by a digital replication of the baseband signal together with a digital spectral phase mask. This technique provides encryption and steganography as it exclusively allows the eligible user to obtain a considerable processing-gain, and to recover extremely low OSNR signals. In this work the secured channel is explored under stringent network conditions. A stealth transmission was tested between two high OSNR public channels, separated 50 GHz apart: Unshaped 25 Gbps NRZ channel and digitally shaped coherent PM-QPSK 112 Gbps channel. Although it is significantly overlapped by adjacent channels and covered by the ASE noise, we demonstrate error-free detection of the secured channel, without significant effect on the commercial channels.

Stealth and secured optical coherent transmission using a gain switched frequency comb and multi-homodyne coherent detection

Eyal Wohlgemuth, Yaron Yoffe, Pantea Nadimi Goki +7 more

A novel all-optical stealth and secured transmission is proposed and demonstrated. Spectral replicas of the covert signal are carried by multiple tones of a gain switched optical frequency comb, optically coded with spectral phase mask, and concealed below EDFA's noise. The secured signal's spectrum is spread far beyond the bandwidth of a coherent receiver, thus forcing real time all-optical processing. An unauthorized user, who does not possess knowledge on the phase mask, can only obtain a noisy and distorted signal, that cannot be improved by post-processing. On the other hand, the authorized user decodes the signal using an inverse spectral phase mask and achieves a substantial optical processing gain via multi-homodyne coherent detection. A transmission of 20 Gbps under negative -7.5 dB OSNR is demonstrated here, yielding error-free detection by the eligible user.

Photonic Layer Encryption in High Speed Optical Communications

Dan Sadot, Eyal Wohlgemuth, Ido Attia +4 more

Combining multi-THz optical spectrum spreading, photonic phase encoding, and negative optical signal-to-noise ratio (OSNR) transmission, forms photonic shield that prevents data recording for offline deciphering. This supports post-quantum security by eliminating raw data availability for quantum computers processing.

Temporal phase mask encrypted optical steganography carried by amplified spontaneous emission noise

Ben Wu, Zhenxing Wang, Bhavin J. Shastri +3 more

A temporal phase mask encryption method is proposed and experimentally demonstrated to improve the security of the stealth channel in an optical steganography system. The stealth channel is protected in two levels. In the first level, the data is carried by amplified spontaneous emission (ASE) noise, which cannot be detected in either the time domain or spectral domain. In the second level, even if the eavesdropper suspects the existence of the stealth channel, each data bit is covered by a fast changing phase mask. The phase mask code is always combined with the wide band noise from ASE. Without knowing the right phase mask code to recover the stealth data, the eavesdropper can only receive the noise like signal with randomized phase.
