Caracterización de un mensajero caótico binario con ruido en el canal: simulación y experimentación

R. Núñez-Pérez

Abstract


A binary chaotic messenger is characterized, based on parameters' commutation, using simulation and experimental procedures to explore his real encrypted communication capacity. The characteristics to find out are: a) Parameter minimum change in such a way the change, of synchronization chaotic signal, be invisible to some spy at the noisy channel, and b) Noise maximum level and c) Time delays allow just to make reliable the binary information recovery. Because, the noisy channel allow hardly the messenger studied right performance, the solution is through a new digital chaotic messenger

Keywords


Chua's circuit; synchronization of chaotics circuits; parameter commutation; channel noise; robust encrypted communication
