We explore the problem of evaluating the practical effectiveness of hidden signal transmission under chaotic carrier. As a signal carrier we use the Shimizu-Morioka chaotic oscillation generator. The useful signal is embedded into chaotic carrier by nonlinear modulation on chaotic generator parameters. The problem is to detect a steganography property for chaotic system nonlinear parametric modulation. The pseudo-random signal in the communication channel is analyzed for the presence of a mixed useful signal in it by Fourier series and by method of autocorrelation. The conclusion about the steganography of the method of hidden information transfer is given. The presented study is a part of chaotic carrier data transmission system design approach with useful signal reconstruction at receiver side by using nonlinear synergetic state observer developed in our previous publications. |
