Light dispersion by casual materials used for creation of the protected communication

Researchers used for enciphering of data light distortion when passing through various materials. Engineers from Tvente's University Twente in Netherlands developed a method of creation of superconfidential optical communication with help two layers casual materials. Technology will be suitable for a bidirectional high-speed wireless communication (LiFi) and fiber-optical networks. Researchers showed that casual materials, such as a paint coat, a sheet of paper or the glass lens — increase privacy of communication, ciphering the message. When light passes through these casual materials, it...
