The Optimization Scheme of Chaotic Masking Secure Communication Based on Lorenz System

This research gives a new improvement scheme of Lorenz signal based on chaotic masking secure communication, which improves the notable features of Lorenz signal and the confidentiality of transmission signal in channel. The scheme here mainly changes the properties of chaotic signal in both time and frequency domains, which makes the masking signal in channel more like noise. This paper also does simulations and comparisons of these two schemes, which verifies that this new chaotic masking optimization scheme based on Lorenz system realizes the optimization for signals in both time and frequency domains, and the synchronization in chaotic masking secure communication.
