Study and Simulation of a Chaos Generator

In our work we have presented chaotic systems which are non-linear deterministic systems that are aperiodic and very sensitive to initial conditions. Since it was discovered that two chaotic systems can synchronize significant interest has been given to the use of these systems to secure transmissions. This attention is due to their unpredictability which exceeds that of conventional transmission systems and to their simplicity of implementation. We have focused on nonlinear dynamical systems the notion of attractors cryptography chaos and the chaos generator. The main objective of this study is the exploitation of chaotic systems or generators in secure transmissions. For this purpose we have studied the main techniques of transmission by chaos. Then we simulated the chaos generator analogically and numerically and finally we interpreted the results.
