Image encryption provides confidentiality to images by transforming them into
unrecognizable forms that resemble white noise. Digital chaos is one of the areas used to …

Recently, a chaotic image encryption algorithm based on information entropy (IEAIE) was
proposed. This paper scrutinizes the security properties of the algorithm and evaluates the …

Privacy preservation has become a prerequisite for modern applications in the cloud, social
media, Internet of things (IoT), and E-healthcare systems. In general, health and medical …

Image encryption is an essential method for ensuring confidentiality during transmission on
open channels. Digital images have a high correlation with large redundant data, requiring …

Image encryption protects visual information by transforming images into an
incomprehensible form. Chaotic systems are used to design image ciphers due to properties …

The need for medical image encryption is increasingly pronounced, for example, to
safeguard the privacy of the patients' medical imaging data. In this article, a novel deep …

In this paper, a new and efficient pixel-level image encryption algorithm is presented. In
contrast to the traditional permutation–diffusion architecture, the proposed method enhances …

Transmission of the information in any form requires security. Security protocols used for
communication rely on the use of random numbers. Pseudo-random numbers are required …

Recently, an image block encryption algorithm was proposed based on some well-known
chaotic maps. The authors claim that the encryption algorithm achieves enough security …

This article proposes an improved tent-dynamic cross coupled map lattice, which has
superior ergodicity, broader chaotic range and higher information entropies than cross …
