“…Another chaotic system, the Chua electronic circuit, is also known for sensing and measurement purposes. Korneta et al [7] developed a DC signal sensor based on the stochastic resonance phenomenon, where the Chua circuit was operated with noise activation in a chaotic range between two coexisting single scroll attractors. This study was later complemented by resistance sensing [8], which allows temperature or light intensity measurements using thermistors or photoresistors, respectively.…”

A remarkable feature of chaotic systems is high sensitivity, which makes them applicable to the construction of sensing devices. Various sensors can be developed based on chaotic oscillators, e.g., metal detectors, salinometers, inductive sensors, and optical sensors. Our study investigates the properties of the metal detector based on Sprott Case N chaotic oscillator equipped with a single inductive coil. A key feature of this circuit is the ability to operate in two modes: chaotic and spiking chaotic oscillations. The last fact makes it possible to consider this circuit as an arti-

“…So far, based on the above 1D chaotic maps, such as the Logistic map and the Tent map [22][23][24], and 2D chaotic systems, such as the Henon map [25][26][27][28], and 3D chaotic systems such as the Rossler chaotic attractor [29,30], the Chua chaotic system [31,32] and the Chen chaotic system [33][34][35], the applications of chaotic systems in image encryption schemes have been relatively mature in chaos researches and developments. However, the fractional-order chaotic systems have more complex dynamic behaviors and mathematical explanations than the above integer order chaotic systems, so they have higher degrees of non-linearity [36].…”

In this paper, a novel image encryption scheme based on a fractional-order Henon chaotic map, a two-dimensional (2D) Discrete Wavelet Transform (DWT) and a four-dimensional (4D) hyperchaotic system is proposed. Firstly, the original image is transformed and scrambled by the 2D DWT, and then the image is shuffled with the fractional-order Henon chaotic time series. Finally, the shuffled image is diffused and encrypted by the 4D hyperchaos system. Through the application of DWT and high-low dimensional chaotic systems, the encryption effect of this algorithm is better than those done by single or ordinary chaotic encryption algorithm, and it has a larger key space and higher security. The experimental tests show that the system has good statistical characteristics, such as histogram analysis, correlation coefficient analysis, key space and key sensitivity, information entropy analysis and so on. The encryption algorithm also passes the relevant security attack tests with good security.

“…At present, research on 1D chaos, such as Logistic mapping [ 5 , 6 , 7 ]; 2D chaos, such as Henon mapping [ 8 , 9 , 10 ]; and 3D chaos, such as Rossler chaotic attractor [ 11 , 12 , 13 ], Chua [ 14 , 15 , 16 ], and Chen [ 17 , 18 , 19 ], have been very extensive and mature. With the development of chaos theory, many people began to study high-dimensional chaotic attractors, such as 4D chaotic attractor subsystems [ 20 , 21 , 22 , 23 ], 5D chaotic attractor subsystems [ 24 , 25 , 26 , 27 ], and 6D chaotic attractor subsystems [ 28 ].…”

In this paper, a new 4D hyperchaotic system is generated. The dynamic properties of attractor phase space, local stability, poincare section, periodic attractor, quasi-periodic attractor, chaotic attractor, bifurcation diagram, and Lyapunov index are analyzed. The hyperchaotic system is normalized and binary serialized, and the binary hyperchaotic stream generated by the system is statistically tested and entropy analyzed. Finally, the hyperchaotic binary stream is applied to the gray image encryption. The histogram, correlation coefficient, entropy test, and security analysis show that the hyperchaotic system has good random characteristics and can be applied to the gray image encryption.
