In the research of multi-image encryption (MIE), the image type and size are important
factors that limit the algorithm design. For this reason, the multi-image (MI) hybrid encryption …

The memristor has received much attention in recent years because of its natural
nonlinearity, but the research on discrete memristor is just beginning. For this reason, a new …

The construction of multi-scroll chaotic systems has been a hot research topic in recent
years. In this paper, a four-dimensional multi-scroll chaotic system is established on the …

This paper designs a new medical image encryption scheme based on a new hyperchaotic
map, which exhibits excellent security and high efficiency that can be applied to medical …

The nonlinear characteristics are studied in a new 4D Hopfield neural network model with
two nonlinear synaptic weights in this paper. The synaptic function is modeled by …

The exponential function is one of the basic elementary functions, which plays an
irreplaceable role in mathematics and is also widely used in practical activities such as life …

This paper proposes a high-quality color image compression-encryption scheme based on
chaos and block permutation. In this scheme, the color digital image is first converted and …

In this paper, an image cryptosystem based on genetic central dogma (GCD), Knuth–Morria–
Pratt (KMP) algorithm and a chaotic system is developed. The KMP algorithm is firstly used …

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 …

A chaotic colour image cryptosystem frame with deep learning is proposed in this paper.
First, we choose a chaotic system, after which a long short-term memory network is used to …
