An image encryption scheme based on a four-wing hyperchaotic system combined with
compressed sensing and DNA coding is proposed. The scheme uses compressed sensing …

In the field of frontier research, information security has received a lot of interest, but in the
field of information security algorithm, the introduction of decimals makes it impossible to …

A new improved three-dimensional continuous chaotic system (ImproBsys) is designed in
this paper. It can achieve from an ordinary chaotic state to a hyperchaotic state, that is …

With the development of telemedicine diagnosis technology, the collection, storage, and
transmission of medical data has become a pivotal problem. To solve these problems, in …

Recently, some visually secure image encryption schemes using compressive sensing (CS)
have been developed to protect images with visual security, where the images are first …

In this paper, a new four-dimensional chaotic system derived from the continuous Hopfield
neural network (CHNN) model is designed, and the weight parameters are optimized to …

Aiming at the deficiencies of existing image compression-encryption algorithms, such as
unstable reconstruction performance and weak crypticity, a novel visually secure image …

The design and utilization of suitable fractal structures is one of the prominent areas of
security for the protection of digital data. This paper proposes a generalized fusion fractal …

The present work studies a novel efficient compressed based cryptosystem which combines
a dynamical parameter coming from high dimensional system, a dynamics S-box and a 2D …

An adaptive reversible image-data hiding (ARIdH) algorithm is proposed. First, the variance
of the secret plain image is calculated and taken as feature values, by a new integer …
