Images contain very sensitive and confidential information. Because images play a
significant role in many applications such as military communication, remote‐sensing, and …

Image encryption is an effective way to protect image data. However, existing image
encryption algorithms are still unable to strike a good balance between security and …

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 …

A 5D memristive chaotic system is proposed in this paper. The essential characteristics and
dynamic behavior of the obtained system are analyzed with the help of numerical simulation …

This paper presents an image encryption scheme with data and appearance security, by
adopting inter-intra-block scrambling and weighted diffusion. The 2D robust hyper-chaotic …

As a medium that can convey information vividly, the application of digital images is
increasingly widespread. Under various application environments, researchers are …

In the modern block cipher, the substitution box (S-box) is a nonlinear constituent that plays
a substantial role to create the confusion in ciphertext. S-boxes with low value of differential …

There are several issues with existing chaotic encryption schemes for images. These
include singularity, unidirectionality, and the complexity of the algorithm. The result is that …

To ensure the safe and reliable transmission of images on public channels, this paper
proposes a dual-domain image encryption algorithm based on hyperchaos and dynamic …

Memristors have brought new driving force to the development of chaos theory for their
intrinsic nonlinearity. Thus, it becomes an attractive research topic to build novel memristive …
