Discrete memristors can be used to construct chaotic and hyperchaotic mapping models by
self-feedback or coupling method, but these constructed maps do not have multistability or …

To solve the problems of low efficiency and poor resistance to attack, this paper proposes
the multi-image encryption algorithm based on Haar wavelet transform and 3D shuffling …

The data space for audio signals is large, the correlation is strong, and the traditional
encryption algorithm cannot meet the needs of efficiency and safety. To solve this problem …

In recent years, newly proposed fractal-fractional calculus operators have been used to
predict the chaotic behavior of some attractors, and the new operators can capture self …

The discrete memristor has aroused increasing interest due to its application prospects. The
theory of discrete memory resistors is gradually being refined. In this paper, the generic …

Recently, fractional calculus theory has been deeply studied, and fractional-order chaotic
systems have attracted much attention from scholars because of their rich dynamic …

In recent years, chaotic systems have been widely used in several engineering fields. In this
paper, an image encryption algorithm for multi-attractor coexistence-spherical chaotic …

Fractals and chaos are inextricably linked, and relevant study has been done on both.
However, the studies that combine fractals and chaotic systems to produce multi-scroll or …

Multistable dynamics analysis of complex chaotic systems is an important problem in the
field of chaotic communication security. In this paper, a new hyperchaotic complex Lü …

The discrete memristor has aroused increasing interest. In this paper, two discrete
