Experts from the Ben-Gurion University of the Negev (Israel) presented the world's first optical "invisible" encryption, which provides much more reliable data protection during transmission than the technologies used today.

The new technology was presented at the Cybertech Global Tel Aviv conference, held January 28-30 in Tel Aviv.

“We have developed a solution for end-to-end encryption, transmission, decryption and detection of data using optics, not numbers,” said Dan Sadot, head of the optical communications research laboratory.

Using standard optical equipment, the research team made the light transmitted over fiber optic cables "invisible." The method presented by the researchers is to use multiple colors to transmit a large data stream instead of a single color of the spectrum within the bandwidth of the optical spectrum, which is 1000 times wider than the digital one. This deliberately creates many weaker streams of data hidden in noise that cannot be detected.

Noise occurs in any type of data transmission, be it electronic, digital or fiber optic. Researchers have succeeded in transmitting weak encrypted signals at high noise levels, and these signals cannot be detected.

“The breakthrough innovation is that if you can't find it, you can't steal it. Since the eavesdropper can neither read nor even know about the existence of the transmitted signals, our optical invisible data transmission provides the highest level of privacy and security for applications working with sensitive data, ”said Sadot.
