Chaos-based image encryption has become a prominent area of research in recent years. In
comparison to ordinary chaotic systems, fractional-order chaotic systems tend to have a …

Recently, to offer better protection for images, new image encryption (IE) algorithms have
been continuously proposed. However, these algorithms still exhibit some problems, such …

The quality of encryption is dependent on the complexity of the confusion-diffusion pattern
and the quality of the keystream employed. To enhance complexity and randomness, this …

With the development of memristor, memristive chaotic systems have attracted attention, but
many of them have divergence problems. To solve this problem, in this paper, a universal …

In this article, an improved memristive Hénon map is proposed by using the state variable
difference instead of the state variable itself as the input of a discrete memristor. As a result …

Nowadays, the utilization of memristors to enhance the dynamical properties of chaotic
systems has become a popular research topic. In this paper, we present the design of a …

Recently, an image encryption scheme based on a 2D hyperchaotic map is proposed. It
adopts the permutation–diffusion architecture and consists of three steps, which are …

To protect image privacy in real-time transmission, a fast chaotic image encryption algorithm
using a novel divide and conquer diffusion strategy is proposed in this paper. Firstly, a fast …

Researchers concentrate on data security using cryptography, using different approaches to
protect confidential data, such as digital images holding private information. They use …
