In this paper, a novel grayscale image cryptosystem based on hybrid chaotic maps is
proposed. The scheme employs both confusion phase to scramble the location of pixels and …

In this paper, a novel color image encryption with heterogeneous bit-permutation and
correlated chaos is proposed. Considering the difference of information amounts between …

This paper proposes a new chaotic cipher algorithm for efficient and secure image content
preservation, this method is specialized for both standard and medical images, and it …

This paper presents a novel encryption scheme based on genetic operations and Mixed
Linear-Nonlinear Coupled Logistic Map Lattice (MLNCML) spatiotemporal chaotic system …

In graph theory, Hamiltonian path refers to the path that visits each vertex exactly once. In
this paper, we designed a method to generate random Hamiltonian path within digital …

Communication networks, play a major role in keeping us connected and sharing the details
of our lives with each other. The main driver of multimedia data transmission is to enhance …

Smart devices, embedded in daily life, have limited memory, power, and processing
capabilities, making traditional cryptography impractical and driving the development of …

In this paper, a new image encryption algorithm is introduced for encrypting grayscale digital
images of any size. To improve the encryption evaluation parameters, we suggested that the …

The fast development of image encryption requires performance evaluation metrics.
Traditional metrics like entropy do not consider the correlation between local pixel and its …
