A two-dimensional cross-mode hyperchaotic map based on logistic and sine maps (2D-
CLSS) is presented. The hyperchaotic map consists of a logistic map and two sine maps …

In accordance with the principle that the cube graph can be obtained by superimposing
planes, a multiple-image encryption scheme based on hyperchaotic map and 3D cube is …

Designing a low-dimensional discrete map to generate chaotic sequence with the properties
of high randomness and without chaos degradation is an attractive but challenging issue …

In this paper, a new improved Lorenz system (ImproLS) is designed with a better behavior
due to a larger positive Lyapunov exponent. Then, an asymmetric image encryption scheme …

Due to the security requirement brought by the rapid development of electronic medical, this
paper proposes an encryption algorithm for multiple medical images. The algorithm can not …

A nonlinear optical multi-image encryption scheme based on chaotic system and two-
dimensional linear canonical transform (2D LCT) is designed. Firstly, the low-frequency sub …

To improve the encryption quality and increase the speed of transmission over the internet,
this study aims to provide a fast secure multiple-image encryption (MIE) algorithm based on …

The growth and popularization of network and multimedia technologies have led to an
increase in digital data over the internet. Most of the data is confidential and requires an …

In the past two decades, we have seen the proliferation of Internet and its applications. The
information exchange happens via images, videos, texts, audio clips, etc. Medical experts …
