Paper Abstract

The paper describes novel method for securing fibre data communication. We developed and studied a method for optical encryption of information transmitted with a traditional fibre link. The presented encryption method uses a spatial light modulator which converts light pulses representing original data into pseudo-random patterns. A linear combination of light pulses with pseudo-random patterns provides a required encryption performance. The main element of the encryptor is the spatial light modulator which comprises a matrix of cells selectively transmitting or blocking the light beam depending on the pseudo-random configuration of cells. The encrypted information is transmitted through the optical fibre. The decryption process relies on a computational solving of linear program or greedy pursuit. The paper present a brief description of the method and theoretical analysis. A physical model concept of the method is also presented.
