Synchronization of Hyper-Chaotic Lorenz System and its Application in Secure Communication
Synchronization of hyper-chaotic Lorenz system and its application in secure communication is studied. Based on the Lyapunov stability, an active nonlinear controller is presented to achieve synchronization of the drive system and the response system. By the conversion functions, the useful signal is modulated into the drive system, and then a secure communication based on hyper-chaotic masking is derived, which can quickly recover the useful signal from the receiver system. Simulation results illustrate the effectiveness of the proposed method.
