Analog electronic circuit design of the Cao 4D hyperchaotic finance system

Abstract

Chaotic and hyperchaotic systems have been used in different fields of science in recent years. Many chaotic and hyperchaotic systems with different behaviors have been introduced in the literature. Especially in chaotic system based encryption, random number generator and communication applications, hyperchaotic systems are more preferred because of their more complex characteristics. The chaotic and hyperchaotic systems introduced in the literature are generally presented only as numerical simulation. However, it is necessary to design the electronic circuit for the use of the systems in real applications. In this study, numerical simulation results of four-dimensional (4D) hyperchaotic finance system introduced by Cao in 2018 were obtained and then analog electronic circuit design was realized. Numerical simulation results and designed electronic circuit outputs have confirmed each other. As a result, it is ensured that Cao 4D hyperchaotic finance system can be used in real engineering applications.
