According to its complex properties like ergodicity, unpredictability, and sensitivity to its initial states, chaotic systems are attracting more and more attention and are widely used for security purposes. Moreover, the chaotic signals are considered suitable for spread spectrum modulation due to their wideband properties. It is able to reduce the peak to average power ratio (PAPA). This paper presents a new Dynamic Diffeo-Difference Multi-Dimensional (DDD-MD) system. It is used as a key for a new cryptosystem designed based on the chaotic stream segmentation (CSS) method. The proposed system provides the best trade-off between efficiency, robustness, and high data rate transmission. The behavior of the proposed chaotic system is evaluated numerically by analyzing the Lyapunov exponent spectrum, complexity, and attractor phase diagram. Besides, it is practically assessed based on the principle of system circuit design; the circuit diagram of the system is prepared and simulated by Multisim, which shows high consistency with the numerical simulation. These evaluations show that the proposed system has a rich dynamics behavior to be realized in an encryption system and provides a foundation for many engineering and physical applications.
