BGN Technologies, Ben-Gurion University of the Negev’s technology transfer company, plans to introduce a new all-optical data encryption technique at the Cybertech Global Tel Aviv conference that will be held January 28-30, 2020 in Tel Aviv, Israel.
The approach spreads optical transmission power across multiple wavelengths to hide signals in optical noise and employs an optical phase mask to prevent decryption without the proper key.

The “stealthy” process involves spreading transmission power across many wavelengths within the optical spectrum (1000X than digital approaches, according to BGN). The amount of optical transmission power in a given wavelength is too small to be detected within optical noise.

“Basically, the innovative breakthrough is that if you can’t detect it, you can’t steal it,” Prof. Sadot explained. “Because an eavesdropper can neither read the data nor even detect the existence of the transmitted signal, our optical stealth transmission provides the highest level of privacy and security for sensitive data applications.”
