Chaotic Masking via Synchronization System based on Combined Type of Synchronization and Novel Hyperchaotic Model

This paper presents a synthesis and application of a hyperchaotic synchronization system for secure communication using chaotic masking. Synchronization scheme between two identical novel mathematical models of a fourth-order hyperchaotic systems, is designed. The chosen type of synchronization combines projective, marginal and hybrid chaotic synchronizations. Active control is synthesized, based on the second Lyapunov stability law. The synchronization scheme is studied in Simulink environment, and the graphical results are displayed using MATLAB. This approach enhances the security and efficiency of data transmission, as sensitive information is concealed within a chaotic signal, making unauthorized decoding challenging. The main functional dependencies and the obtained graphical representations demonstrate that this combined synchronization method, when integrated with a hyperchaotic system, provides an effective and robust encryption solution that withstands some noise interferences, ensuring secure, efficient data transmission across open communication channels.
