This paper summarizes the symmetric image encryption results of 27 different algorithms,
which include substitution-only, permutation-only or both phases. The cores of these …

Chaos-based cryptosystems have been an active area of research in recent years. Although
these algorithms are not standardized like AES, DES, RSA, etc., chaos-based cryptosystems …

In recent decades, image encryption, as one of the significant information security fields, has
attracted many researchers and scientists. However, several studies have been performed …

Images play a substantial role in various applications such as medical imaging, satellite
imaging, and military communications. These images often contain confidential and …

This paper proposes a novel confusion and diffusion method for image encryption. One
innovation is to confuse the pixels by transforming the nucleotide into its base pair for …

We designed a stream-cipher algorithm based on one-time keys and robust chaotic maps, in
order to get high security and improve the dynamical degradation. We utilized the piecewise …

A new color image encryption algorithm based on DNA (Deoxyribonucleic acid) sequence
addition operation is presented. Firstly, three DNA sequence matrices are obtained by …

A new image encryption scheme based on DNA sequence addition operation and chaos is
presented. First, a DNA sequence matrix is obtained by encoding the original image, then …

In recent years, a variety of chaos-based image cryptosystems have been proposed. Owing
to the exceptionally desirable properties of mixing and sensitivity to initial conditions and …

This paper proposes a novel encryption scheme based on combining multiple chaotic maps
to ensure the safe transmission of medical images. The proposed scheme uses three …
