Image encryption techniques play a significant role in multimedia applications to secure and
authenticate digital images. This paper presents a comprehensive study of various image …

Nowadays, security in data transfer is of special importance. Images are of the most
attractive kinds of data in the encryption domain. Color images are more attractive than the …

Image encryption provides confidentiality to images by transforming them into
unrecognizable forms that resemble white noise. Digital chaos is one of the areas used to …

Image encryption is a straightforward strategy to protect digital images by transforming
images into unrecognized ones. The chaos theory is a widely used technology for image …

In this paper, a novel image encryption approach based on permutation-substitution (SP)
network and chaotic systems is proposed. It consists of four cryptographic phases: diffusion …

In this paper, we introduce a novel color image encryption algorithm based on DNA
sequence operations, one-time keys and the spatiotemporal chaos. Firstly, the key streams …

Four chaotic maps are used herein as case study to design an embedded cryptosystem
based on a pseudo-random number generator (PRNG). The randomness of the sequences …

Due to the potential security problem about key management and distribution for the
symmetric image encryption schemes, a novel asymmetric image encryption method is …

It is generally recognized that encrypting an original image into meaningless cipher image is
an ideal method to protect image information. However, during transmission, the …

This paper proposes a new lossless encryption algorithm for color images based on a six-
dimensional (6D) hyperchaotic system and the two-dimensional (2D) discrete wavelet …
