Privacy is a serious concern related to sharing videos or images among people over the
Internet. As a method to preserve images' privacy, chaos-based image encryption algorithms …

Due to social networks, demand for sharing multimedia data is significantly increased in last
decade. However, lower complexity and frequent security breaches on public network such …

Due to the significant properties of unpredictability, ergodicity, and initial state sensitivity,
chaotic system is widely used as a useful tool in image encryption. In this paper, we propose …

In modern-day block ciphers, the role of substitution-boxes is to transform the plaintext data
nonlinearly to generate ciphertext data with sufficient confusion. It has been well-confirmed …

Chaos-based encryption schemes have attracted many researchers around the world in the
digital image security domain. Digital images can be secured using existing chaotic maps …

The evolution of wireless and mobile communication from 0G to the upcoming 5G gives rise
to data sharing through the Internet. This data transfer via open public networks are …

In this work, we propose a novel 3D chaotic map obtained by coupling the piecewise and
logistic maps. Showing excellent properties, like a high randomness, a high complexity and …

Chaotic maps are very important for establishing chaos-based image encryption systems.
This paper introduces a coupling chaotic system based on a certain unit transform, which …

A number of image encryption techniques have been proposed in recent years. These
techniques use either spatial or transform domain image processing. A major challenge …

Visual selective image encryption can both improve the efficiency of the image encryption
algorithm and reduce the frequency and severity of attacks against data. In this article, a new …
