“…How to ensure security and privacy in the IoT and the Industrial Internet of Things (IIoT) is related to network reliability and network security [53][54][55]. Due to the initial value sensitivity, randomness and unpredictability of chaotic systems, image encryption [56][57][58][59][60][61][62], random number generator [63][64][65] and secure communication [66][67][68][69][70] based on chaos have become popular research hotspots in the field of information security.…”

Fractional-order chaotic systems are widely used in the field of encryption because of its initial value sensitivity and historical memory. In this paper, the fractional-order definition of Caputo is introduced based on a nonideal flux-controlled memristive Hopfield neural network model, when changing the parameters of the fractional-order memristive Hopfield neural network (FMHNN) can generate a different amount of multi-scroll attractors. Some dynamical behaviors are investigated by numerical simulation, especially analyzed coexistence and bifurcation under different orders and different coupling strengths. The results show that the chaotic system of FMHNN has abundant dynamic behaviors. In addition, a chaotic audio encryption scheme under a Message Queueing Telemetry Transport (MQTT) protocol is proposed and implemented by Raspberry Pi; the audio encryption system based on FMHNN has a broad future in intelligent home and other IoT applications.

“…[6] To meet the secure encryption and transmission of images, there are many scholars devoted to IE algorithms. [7][8][9][10][11][12] Among many IE techniques, the chaos theory-based IE has attracted much attention for its good performance. [13][14][15][16] The prominent characteristics with chaotic systems are their sensitivity to the initial parameters, pseudo-randomness, [17] which provides a lot of inspiration and ideas for designs of IE algorithms.…”

Combining hyperchaotic map, cross-plane operation and gene theory, a color image encryption scheme is devised. First, the hyperchaotic map used in the encryption scheme is analyzed and studied. On the basis of the dynamics of hyperchaotic map, a color image encryption scheme is designed. At the end of the encryption process, a DNA mutation operation is used to increase the encoding images’ randomness and improve the encryption algorithm’s security. Finally, simulation experiments, performance analysis, and attack tests are performed to prove its effectiveness and security of the designed algorithm. The research work in this paper offers the possibility of applying chaos theory and gene theory in image encryption.

In this paper, a novel fractional-order hyperchaotic complex system is proposed by introducing the Caputo fractional-order derivative operator and a constant term to the complex simplified Lorenz system. The proposed system has different numbers of equilibria for different ranges of parameters. The dynamics of the proposed system is investigated by means of phase portraits, Lyapunov exponents, bifurcation diagrams, and basins of attraction. The research results show that it displays abundant dynamical characteristics. Particularly, the phenomenon of extreme multistability as well as hidden attractors are discovered. In addition, the complex generalized projective synchronization is implemented between two fractional-order hyperchaotic complex systems with different fractional orders. Based on the fractional Lyapunov stability theorem, the synchronization controllers are designed, and the theoretical results are verified and demonstrated by the numerical simulations. It lays the foundation for the practical applications of the proposed system.
