"An Israeli startup that has developed technology to stop data being stolen from internet cables has emerged from stealth with a total of $26 million in funding. CyberRidge says its technology manipulates light to conceal data as it travels through fiber-optic cables on the seabed or on land. If an adversary - like a nation state - cuts the cables and tries to steal the data, they would only capture "random noise," Dan Sadot, the CEO and founder of CyberRidge, told Business Insider."
"Subsea cables, which are typically about as thick as a garden hose, are the backbone of the internet and crucial to the world's economy. Data is already encrypted as it travels through sprawling fiber-optic cables around the world. However, it can be siphoned off and stored with the intention of decrypting it in the future with powerful quantum computers, which are expected to crack today's encryption standards."
CyberRidge developed optical technology that conceals data traveling through fiber-optic cables by manipulating light so intercepted signals appear as random noise. The company offers a hardware device that sits at each cable end and requires a recomposition process using a photonic key that changes every fraction of a second. The approach aims to prevent adversaries who cut cables from siphoning usable data and complements existing encryption to guard against future quantum decryption. Potential customers include telecommunications carriers and hyperscale cloud providers. The company emerged from a concept encouraged by an Israeli intelligence unit and raised $26 million in funding.
