Encriptador experimental retroalimentado de Lorenz con parámetros desiguales

R. Núñez


The Lorenz encrypter circuit is characterized and specified to show experimental confirmation that with message and random noise feedback at the transmitter it is possible to achieve a high quality message recovery, even though of transmitter and receiver Rayleigh parameters have a 10% of mismatching, and a channel random noise of the same magnitude of the message. This modified chaos-based communication scheme puts away from the Carroll and Pecora (1991) requirement that says that the circuits to synchronize must be identical. In conclusion, the encryption robustness indicates that the proposed scheme can be built with low cost components and therefore could be appropiate to academics purposes. It is need to performance more studies regarding to electrical noise and long time stability for confidentially to use the circuit in real applications for transmission of messages hidden by chaotic signals.
