Israeli Researchers Develop ‘Stealthy Fiber Optics’
Researchers at Ben Gurion University of the Negev and Bar Ilan University have developed an innovative cybersecurity system called “stealthy fiber optic communications,” according to a report in Arutz Sheva.
The new encryption method enables stealthy transmission of any optical communications signal by spreading the transmission below the noise level in both time and frequency domains.
“It is analogous to many soft sounds of a lovely symphony scattered through a recording of background noise,” said the researchers. “The authorized user who knows the spreading key is the only one able to detect and enjoy the symphony without the noisy background.
“It should be noted that analysis shows that it will take [an exponential number of] years for an eavesdropper to break the encryption key — which means that eavesdropping is very hard,” they explained.
A hacker trying to pick up the transmitted signal catches only noise, since the signal is hidden below the noise level.
The system, currently in the patenting process, was developed by Ben Gurion University of the Negev’s Prof. Dan Sadot and Prof. Ze’ev Zalevsky of Bar Ilan University together with PhD student Tomer Yeminy.
