In recent years, a large amount of work on chaos-based cryptosystems have been
published. However, many of the proposed schemes fail to explain or do not possess a …

When chaotic systems are realized with finite precisions in digital computers, their dynamical
properties are often found to be entirely different from the original versions in the continuous …

Over the past years, an enormous variety of different chaos-based image and video
encryption algorithms have been proposed and published. While any algorithm published …

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 …

Based on the high-dimension Lorenz chaotic system and perceptron model within a neural
network, a chaotic image encryption system with a perceptron model is proposed. This …

This paper is devoted to the analysis of the impact of chaos-based techniques on block
encryption ciphers. We present several chaos based ciphers. Using the well-known …

This paper suggests a unique image encryption scheme based on key-based block
ciphering followed by shuffling of ciphered bytes with variable-sized blocks, which makes …

It is well-known that images are different from texts in many aspects, such as highly
redundancy and correlation, the local structure and the characteristics of amplitude …

In this paper, we propose a new loss-less symmetric image cipher based on the widely used
substitution–diffusion architecture which utilizes chaotic standard and logistic maps. It is …

The new image encryption architecture presented in this paper employs a novel circular
inter–intra pixels bit-level permutation strategy. This strategy aims to reduce redundancies …
