The secure key generation is the predominant requirement of an image encryption. Chaotic
maps are often considered by the researchers for secure key generation. However, chaotic …

In this paper, a new and efficient pixel-level image encryption algorithm is presented. In
contrast to the traditional permutation–diffusion architecture, the proposed method enhances …

In this paper, we propose a novel medical image encryption algorithm based on a hybrid
model of deoxyribonucleic acid (DNA) masking, a Secure Hash Algorithm SHA-2 and a new …

This paper proposes an image encryption algorithm based on a chaotic map and
information entropy. Unlike Fridrich's structure, the proposed method contains permutation …

In today's technology world, data security has a great importance. Because each data type
has its own characteristics, there are various methods of providing this security. The main …

This paper proposes a parallel digital image encryption algorithm based on a piecewise
linear chaotic map (PWLCM) and a four-dimensional hyper-chaotic map (FDHCM). Firstly …

Image encryption is a useful technique of image content protection. In this paper, we
propose a novel image encryption algorithm by jointly exploiting random overlapping block …

This paper introduces a new image encryption scheme using a mixing technique as a way to
encrypt one or multiple images of different types and sizes. The mixing model follows a …

These recent years, countless chaos-based image encryption algorithms have been
proposed to meet security needs in real time multimedia communication. However, many of …

In this study, an enhanced quadratic map (EQM) is proposed and has been applied in a new
colour image encryption scheme. The performance evaluations show that the EQM has …
