On the basis of the classic chaos theory, a new memristive chaotic system with hidden attractor was constructed. And the basic dynamic characteristics of the system was analyzed. Based on the system, an analog circuit was designed for simulation. Finally, the synchronization control of the system was explored. The research show that the system has abundant nonlinear behaviors, such as Poincaré mapping, Brownian motion, bifurcation diagram and Lyapunov exponent spectrum. The circuit simulation results are basically consistent with the theoretical analysis and numerical simulation results, which lays a certain foundation for the practical application of the memristive chaotic system. According to the existing theory, a suitable adaptive controller was proposed to achieve synchronization. At the same time, the unknown parameters of the system were identified. The effectiveness of the control method was verified by the numerical simulation.

“…Singh et al (2020) discussed a secure communication application using a new hyperchaotic system with a stable equilibrium [2]. designed a new simple hyperchaotic system with dual memristors and applied it for a secure communication system [3]. Using a hyperchaotic Lorenz system, Ouannas et al (2021) suggested a new secure communication system, which is obtained by combining chaotic modulation, recursive encryption and chaotic masking [4].…”

In this work, we devise a new 5-D hyperchaotic dynamo system by adding two feedback controllers to the Rikitake 2-disk dynamo system (1958). We show that the new 5-D hyperchaotic system does not possess any equilibrium point and deduce that the new 5-D system has a hidden hyperchaotic attractor. Using Multisim, we develop an electronic circuit design of the new 5-D hyperchaotic dynamo system for practical applications. We also exhibit the implementation of the new 5-D hyperchaotic dynamo system by using a field-programmable gate array (FPGA), which requires adders, subtractors and multipliers. The hardware resources are given for the application of three numerical methods, all of them providing results in good agreement with MATLAB simulations. As an application, we devise a dual core high speed hybrid true random number generator (TRNG) using Ring and Heun algorithm based on the new 5-D hyperchaotic oscillator on FPGA. Based on the hyperchaotic features of the proposed 5-D hyperchaotic dynamo system, we suggest a new encryption approach for colour images. Simulation outcomes of the presented encryption approach confirm that our chaotic system has good cryptographic properties and its usability in different cryptographic purposes.
