Block cipher has been one of the most reliable options by which data security is achieved.
The strength of block cipher against various attacks is purely dependent on its confusion …

The vast amount of data generated by various applications necessitates the need for
advanced computing capabilities to process, analyze and extract insights from it. Quantum …

This paper introduces a pioneering, effective data-hiding algorithm using different sizes of
cover images and different types of secret data (image, txt, and audio). The proposed …

Chaotic systems are applicable to image cryptography with their inherent properties.
Unfortunately, in numerous existing chaos-based image cryptography, chaotic systems face …

This paper presents a quantum image steganography algorithm based on HSI color space
embedding technique. To increase the security of sensitive information, a three-dimensional …

The continuous development of the industrial internet of things has raised increasingly high
requirements for the secure storage and transmission of information. Ensuring that image …

At present, multi-image encryption schemes usually require the type, quantity and size of
images to be fixed, and there are many restrictions. Therefore, this paper proposes a multi …

In this paper, we propose a quantum steganography scheme with a color image as the cover
image. In order to enhance the security of the embedded information, Arnold disambiguation …

In many situations, the dual protection of image information transmission security and
identity authentication is required. A quantum encryption and watermarking technique …

A quantum image steganography algorithm based on edge detection is proposed. Firstly, a
new fractal chaotic system with good chaotic properties is proposed to improve the security …
