The unprecedented growth in production and exchange of multimedia over unsecured
channels is overwhelming mathematicians, scientists and engineers to realize secure and …

Many researchers have devoted themselves to studying image encryption based on chaotic
system and have made significant strides in research in recent decades. This paper first …

This paper proposes an efficient image encryption method based on a hybrid of
watermarking and cryptographic techniques. It is based on two-level security for the secure …

In this paper, a distinctive Hybrid Adaptive Image Encryption (HAIE) scheme is proposed that
utilizes some statistical parameters of the plain image like mean and variance to modify the …

Chaos maps are widely used in image encryption systems due to their intrinsic advantages
such as extreme sensitivity to initial values., ergodicity and pseudo-randomness. 1D Logistic …

In response to the problems of high complexity and the large amount of operations of
existing color image encryption algorithms, a low-complexity, low-operation color image …

In this paper, a new four-dimensional hyperchaotic system that has better unpredictability,
more complex dynamic behavior, and a larger key space is proposed. The initial chaos …

Cyber-physical system (CPS) devices like connected vehicles, consumer appliances, and
many other smart devices are built with limited resources like processors and memory …

This paper uses a novel color image stego-crypto technique to enhance the capacity,
security and robustness of data embedding process. The proposed scheme uses a base64 …

In this study, we propose an improved adaptive weighted mean filter (IAWMF) to remove salt-
and-pepper noise. The most prominent advantage of IAWMF is its ability to take into account …
