abstract = {This paper presents the design of a novel secure communication system based on the dynamics of the Lü hyperchaotic system. In the proposed scheme, the information signal is directly embedded into the hyperchaotic trajectories, ensuring a high level of data concealment. To achieve accurate synchronization between the transmitter and the receiver, a predictive control strategy combined with chaotic modulation is employed. This synchronization mechanism enables precise recovery of the embedded information signal. To evaluate the feasibility and robustness of the proposed cryptosystem, a dual validation framework is adopted. Numerical simulations are carried out using MATLAB/Simulink, and hardware-oriented simulations are performed using Multisim. The strong agreement between the numerical and circuit-level results confirms both the effectiveness and the reliability of the proposed approach. Overall, this work demonstrates the significant potential of hyperchaotic systems for secure communication applications.}
