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...
A system-oriented analysis of the encryption efficiency of chaos communication systems consisting of lasers subject to all-optical feedback is presented in this paper. Two codification methods are considered, namely external baseband and subcarrier modulation. The robustness of each codification method to two attack scenarios, which are the filtering of the directly detected signal and the usage of...
