A multiple-image encryption algorithm based on single-channel scrambling, diffusion and
chaotic system is presented in this paper. The initial values of the chaotic system are …

A comprehensive review of symmetry and conditional symmetry is made from the core
conception of symmetry and conditional symmetry. For a dynamical system, the structure of …

This paper proposes a kind of nonvolatile locally active memristor. The three fingerprints for
distinguishing memristor is verified by the stable and coexisting pinched hysteresis loops …

In recent years, image encryption schemes based on optical methods have been extensively
studied. However, possible optical encryption methods in combination with fractional-order …

Many researchers have devoted themselves to studying image encryption based on chaotic
system and have made significant strides in research in recent decades. This paper first …

Previous studies have shown that cyclic neural networks which have no autoexcitation and
are unidirectional cannot generate chaos. Inspired by this finding, the present paper …

In this paper, a color image encryption algorithm is presented, the new algorithm uses
double-layer Joseph's scramble, XOR diffusion, and is built on a laser chaos system. Firstly …

Multi-image encryption has attracted great interest in the era of secret communication,
however, the mixed encryption of gray and color images has been reported rarely …

We devise a color image encryption scheme via combining hyperchaotic map, cross-plane
operation and gene theory. First, the hyperchaotic map used in the encryption scheme is …

The ideal magnetic flux-controlled memristor was introduced into a four-dimensional chaotic
system and combined with fractional calculus theory, and a novel four-dimensional …
