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

In this paper, a chaotic multiple-image encryption algorithm using block scrambling and
dynamic DNA coding is designed. The algorithm can achieve simultaneous encryption of …

In this study, we introduce a refined approach to encrypting 32-bit color images, leveraging
the potential of four 1D chaotic maps–the Logistic map, Tent map, Chebyshev map, and …

In this paper, a novel image encryption algorithm based on a new permutation scheme and
DNA operations are introduced. In our algorithm, SHA 256 and DNA hamming distance …

Since the past few decades, various methods for diagnosis of different diseases have been
introduced in the area of medical science. One such invention is the use of digital images to …

A novel image encryption algorithm using a combination of 4D discrete hyperchaotic map
and DNA encoding is proposed in this work. The used 4D discrete hyperchaotic map has a …

This paper proposes a robust optimization of eight chaotic maps: Logistics, Sine, Gauss,
Circle, Tent, Chebyshev, Singer, and Piecewise Maps, for superior image encryption. The …

The quota traveling salesman problem (QTSP) is a variant of the traveling salesman
problem (TSP), which is a classical optimization problem. In the QTSP, the salesman visits …

In order to prevent unwanted access to sensitive data by unauthorized individuals, color
images are encoded. Because chaotic-deoxyribonucleic acid (chaotic-DNA) encoding can …

This article proposes a novel evolutionary image encryption approach based on an elitist
genetic algorithm, a modified logistic map, and DNA encoding. The initial population …
