In medical information systems, image data can be considered crucial information. As
imaging technology and methods for analyzing medical images advance, there will be a …

Face recognition is a relatively common method humans use to confirm their identity.
Protecting the safe transmission of face images has become a hot issue. This paper …

With the explosion of the generation, transmission and sharing of image data over the
Internet and other unsecured networks, the need for and significance of the development of …

This paper innovatively proposes a high-sensitive cross-channel color image encryption
algorithm (SFHM-IEA) by using two-dimensional hyperchaotic map (2D-SFHM) derived from …

The main contribution is to design a cryptographically keyed strong S-Box construction
method, based on a non-degenerate 3D improved quadratic map (3D-IQM). First, a 3D-IQM …

An asynchronous updating Boolean network is employed to simulate and analyze the gene
expression of a particular tissue or species, revealing the life activity process from a system …

More and more privacy-sensitive images have been produced daily. Chaotic encryption
guarantees that only the targeted receiver can obtain the raw image. Many works perform …

This paper presents a novel framework for generating new chaotic signals for image
encryption that is based on the finite precision of computers. First, we select a system from a …

In this paper, an encryption algorithm based on hyper-chaotic system and bit-level
permutation is proposed. Firstly, the forward diffusion method based on two-dimensional …

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 …
