This study presents an approach for secure communication based on the underactuated synchronization of a 4D-hyperchaotic system recently introduced in the literature. The presence of disturbances is considered in all states of the master and slave systems for a more robust synchronizer. The Lyapunov theory is used to demonstrate the effectiveness of the proposed system, ensuring that the synchronization error is bounded and achieves convergence in a finite time. Also, this work includes computer simulations based on Matlab/Simulink to validate the proposed system, including the master-slave synchronization and the implementation of a secure communication scheme.
