Secure data encryption at the speed of light

US scientists have just announced a new method that allows information to be transmitted over fiber-optic networks at low cost, wide scope of operation and high security.

Princeton University expert Bernard Wu and Evgenii Narimanov said the technique uses the existing fiber optic network to cover the message. In fact, optical fiber systems always contain certain noise and noise in the wavelength of light, so the data will be hidden in the optical noise.

Then, the optical CDMA decoder transmits this pulse in a faded signal range, weaker than the oscillations and noise in the optical fiber network. The receiver will analyze the information based on how the message was originally sent and unzip to the original state.

This technique is very secure and even eavesdropping systems know that a certain message is being transmitted but still cannot be detected.

"Our data encryption method is based on optical CDMA - technology is still being researched and developed - so organizations cannot deploy soon ," Wu said.
