TLDR
In this letter it is demonstrated experimentally how Chua’s circuits can be used to implement a secure communication system that has the advantage of transmitting a spread spectrum signal and is also more secure in the sense that better parameter matching is required in order to recover the signal.Abstract:
In this letter we demonstrate experimentally how Chua’s circuits can be used to implement a secure communication system. This system is compared to another system proposed earlier. This system has the advantage of transmitting a spread spectrum signal and is also more secure in the sense that better parameter matching is required in order to recover the signal. Furthermore, there is less of a problem with loss of synchronization.read more

General approach for chaotic synchronization with applications to communication.
Ljupco Kocarev,Ulrich Parlitz +1 more
TL;DR: This chapter considers an improved encoding method where the information signal is injected into the dynamical system of the transmitter and highlights how to design in a systematic way high-dimensional synchronized systems that may be used for efficient hyperchaotic encoding of information.
