Some Researches for Lorenz-Based Secure Communication in Time and Frequency Domains

Abstract

This paper introduces some results of our researches on Lorenz-based secure communication in time and frequency domains. These researches are focused on the characteristics of Lorenz system and processing it for its application in secure communication. In this paper, it gives the processing methods for Lorenz system, that is, filtering and frequency domain truncation method for test. Then, it also shows the results of Lorenz-based secure communication in time and frequency domains, such as analyzing the time-frequency features of Lorenz signal, quantifying the processed signals and reconstructing chaotic abstractors.
