Several chaos-based image encryption schemes have been proposed in the last decade.
Each encryption scheme has pros and cons regarding its speed, complexity, and security …

In this paper, a new medical image encryption technique based on genetic algorithms acting
at the bit level will be developed. Initially, a transformation to a binary matrix notation of the …

Abstract The Substitution Box (S-Box) plays a critical role in several block cipher
cryptosystems due to its ability to provide essential properties of non-linearity and confusion …

In this work, we will propose a new color image encryption technique using chaotic maps
and based on an improved Feistel scheme. This scheme is reinforced by two genetic …

This paper proposes a novel image encryption method, which is based on an improvement
of the classic HILL technique using the 2D logistic map. First vectorize the original image …

The Most multimedia files, especially those containing private information are images. Since
multimedia transmission takes place on public communication channels, it is more …

In this work, a new approach to image encryption is proposed. This crypto system is
composed of two stages of the Hill cipher. First, a passage in vector of the original image is …

This paper proposes a new JPEG image encryption algorithm based on hyperchaotic, mixed
hash, and dynamic DNA to solve the problem of poor robustness and low efficiency in …
