Estudio de la sincronización de sistemas caóticos para garantizar la seguridad de las comunicaciones.

Abstract

Every day millions of communications are performed and the information has become a valuable asset for individuals and institutions. So guaranteeing the security of the information that is transmitted is of vital importance so as not to suffer losses or theft of the it that can cause economic damages and of confidence. Many methods have been researched and developed over the years but most models using techniques which are easily to predict and decoded. Thus techniques that used mathematical models with chaotic behaviors have gained much interest. In this thesis, a study of chaotic signals and their use to ensure the security of communications is presented, in addition is presented a scheme of easy implementation in a microprocessor to perform tests and laboratory practices. In Chapter 1, is made a reference about the general aspects of the research. In Chapter 2 a study of chaotic signals, the applied modulation scheme and the microprocessor used in the experimental scheme is studied. In Chapter 3, several simulations are performed using the Mathematica program to check the behavior of chaotic signals and the logistic map. Chapter 4 presents a proposed scheme of easy implementation to ensure the security of the communication scheme. Finally, in Chapter 5 Conclusions and recommen dations of the research are presented.
