This work studies the dynamics, control and synchronization of hyperchaotic Lorenz-stenflo system and its application to secure communication. The proposed designed nonlinear feedback controller control and globally synchronizes two identical Lorenz-stenflo hyperchaotic systems evolving from different initial conditions with unknown parameters. Adaptive synchronization results were further applied to secure communication. The numerical simulation results were presented to verify the effectiveness of the designed nonlinear controller and its success in secure communication application.
