Abstract

In order to provide an effective method to verify the security of chaotic secure communication system, Wigner-Ville distribution is put forward in this paper to analysis the time frequency energy accumulation characteristics of chaotic system, based on which a blind extraction algorithm is proposed to realize the hidden transmission and effective extraction of signals under chaotic systems. Analysis Wigner-Ville distribution of two typical three dimensional chaotic dynamical systems and simulate to analyze the performance of the algorithm qualitatively and quantitatively. In the end, change the frequency interval to verify the reliability of algorithm.
