ABSTRACT
A traditional approach to transmitting proprietary data consists of encoding a given proprietary message in a nonrandom signal and then hiding that signal in a noise-like background. The random data streams generated by token 1 and token 0 are components for further generation of the smart noise. A smart noise (SN) can be combined with a decoy signal, the latter having a regular nonrandom structure and may be of a larger power than the SN. The essence of the method is transmitting a message over a communication channel using a smart noise having an internal structure associated with this message. If the smart noise consists of several components, and the spectra of these components are predominantly localized in adjacent sections of the spectral window used for transmission, this frequency should be chosen at the boundary of two adjacent sections of the spectral window.
