Chaotic optical communication at high bit rates has attracted great attention because of its potential application in secure communications. In a chaotic optical communication system, a message can participate in the dynamics of the nonlinear system and further affect the characteristics of the chaotic carrier waveform. Message encoding can also change the synchronization quality if an Author: Shuo Tang, Jia‐ming Liu. The monograph begins with a systematic introduction of chaos and chaos synchronization, and then extends to the methodologies and technologies in secure communication system design and implementation. The author combines theoretical frameworks with empirical studies, making the book a pratical reference for both academics and industrial engineers.

Design and Implementation of Secure Chaotic Communication Systems. By Rupak Kharel. Get PDF (4 MB) Abstract. Chaotic systems have properties such as ergodicity, sensitivity to initial conditions/parameter mismatches, mixing property, deterministic dynamics, structure complexity, to mention a few, that map nicely with cryptographic requirements Author: Rupak Kharel. Chaotic signal is generated by the logistic map firstly. Then, chaotic sequence is generated after the symbolic function mapping as follows: where is chaotic signal, is symbolic function, and is chaotic sequence of the th user.. The transmitter is illustrated in Figure 2.A pair of bit is modulated and transmitted in a frame, the th frame, and are transmitted in the first slot, where Author: Gang Zhang, Niting Cui, Tianqi Zhang.

Abstract: In this work, we present results about the implementation of chaotic generators with DSPs, which were programmed in C language. The main idea is about the synthesis of chaotic generators using DSK Texas instrument development card. The Lorenz system, Rössler system and Chua’s circuit were used for this purpose. History. In , Nikola Tesla demonstrated a radio controlled boat in Madison Square Garden that allowed secure communication between transmitter and receiver. One of the most famous systems of secure communication was the Green WWII, Winston Churchill had to discuss vital matters with Franklin D. first, the calls were made using a voice scrambler as this was.
