Encryption of Analog and Digital Signals Through Synchronized Chaotic System

Chaos is an aperiodic long-term behavior in a deterministic system that exhibits sensitively dependent on initial conditions. There are three keywords in this definition, i.e. “aperiodic long-term behavior”, “deterministic” and “sensitive dependence on initial conditions”. “Aperiodic long-term behavior” means that the system’s trajectory in phase space does not settle down to any fixed points, periodic orbits, or quasi-periodic solutions as time tends to infinity. “Deterministic” means the irregular behavior of chaotic systems arises from intrinsic nonlinearities rather than noise. “Sensitive dependence on initial conditions” means that trajectories originating from very nearly identical initial conditions will diverge exponentially quickly.
