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

Image encryption has become the essential way to secure image information with the high
frequency of multimedia information exchange on the Internet. In this paper, an effective …

This paper introduces a method of making a simple and effective chaotic system by using a
difference of the output sequences of two same existing one-dimension (1D) chaotic maps …

Because of the excellent properties of unpredictability, ergodicity and sensitivity to their
parameters and initial values, chaotic maps are widely used in security applications. In this …

This paper introduces a simple and effective chaotic system using a combination of two
existing one-dimension (1D) chaotic maps (seed maps). Simulations and performance …

A novel image encryption algorithm based on double chaotic systems is proposed in this
paper. On account of the limited chaotic range and vulnerability of a single chaotic map, we …

In this paper we propose a new image randomness measure using Shannon entropy over
local image blocks. The proposed local Shannon entropy measure overcomes several …

To improve the randomicity behaviors of some existing chaotic maps, this paper proposes
two integrated chaotic systems (ICS), which conduct cascade, nonlinear combination, and …

In this paper, we propose a novel image encryption method based on logistic chaotic
systems and deep autoencoder. In the encryption phase, first, the plaintext image is …
