Four chaotic maps are used herein as case study to design an embedded cryptosystem
based on a pseudo-random number generator (PRNG). The randomness of the sequences …

It is well known that chaos is unpredictability and sensitivity to initial values and parameters.
It is a best choice for cryptography application. However, the existing chaotic cryptography …

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 …

Many chaos-based image encryption algorithms using low-dimensional chaotic mapping
and permutation diffusion structures have been proposed recently. However, low …

Lots of digital images from different fields distributed in Internet are exposed to various risks,
such as the content leakage, illegal access and use. To solve the problems of weak security …

In this paper, a universal two-dimensional (2D) enhanced cosine coupled model (2D-
ECCM) is first designed, which can construct new 2D chaotic systems using most of the …

Recently, a lot of research has been done in chaotic cryptography field using different kinds
of chaotic systems, like chaotic maps, which are being considered as one of the secure and …

Hundreds of image encryption algorithms have been developed for the security and integrity
of images through the combination of DNA computing and chaotic maps. This combination …

Hundreds of image encryption schemes based on the conventional 2D image space exist in
the literature. Very few were built using the 3D image space. In this study, for better security …

Chaotic theory is being increasingly researched for application in image encryption scheme
(IES). This paper presents a novel two-dimensional cross hyperchaotic Sine-modulation …
