Chaos has been one of the most effective cryptographic sources since it was first used in
image-encryption algorithms. This paper closely examines the development process of …

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 …

In this paper, a novel triple-image encryption and hiding algorithm is proposed by combining
a 2D chaotic system, compressive sensing (CS) and the 3D discrete cosine transform (DCT) …

This paper innovatively proposes a high-sensitive cross-channel color image encryption
algorithm (SFHM-IEA) by using two-dimensional hyperchaotic map (2D-SFHM) derived from …

In this paper, we propose a new method for optical image encryption using fractional Fourier
transform, DNA sequence operation and chaos theory. Random phase masks are generated …

Abstract Information security and authentication are important challenges facing society.
Recent attacks by hackers on the databases of large commercial and financial companies …

To increase the robustness against common attacks, a novel image encryption algorithm is
proposed based on the phase-truncated short-time fractional Fourier transform (PTSTFrFT) …

The paper studies a recently developed evolutionary-based image encryption algorithm. A
novel image encryption algorithm based on a hybrid model of deoxyribonucleic acid (DNA) …

In this paper we review a number of optical image encryption techniques proposed in the
literature inspired by the architecture of the classic optical Double Random Phase Encoding …

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 …
