This paper proposes a secure and energy-efficient Internet of Things (IoT) model for e-
health. The main objective is to secure the transmission and retrieval of biomedical images …

In this paper, an efficient visually meaningful image compression and encryption (VMICE)
scheme is proposed by combining compressive sensing (CS) and Least Significant Bit (LSB) …

We present a simple yet highly dimensional hybrid diode bridge circuit network that can
exhibit complex chaotic behaviours. Further, since our network is characterised by smooth …

This paper introduces an image encryption algorithm shorted as CITSPD, manipulated by
circle index table scrambling and partition diffusion. Firstly, the circle index table is obtained …

Designing efficient and secure cryptosystems has been a preoccupation for many scientists
and engineers for a long time wherein they use chaotic systems to design new …

Due to the potential security problem about key management and distribution for the
symmetric image encryption schemes, a novel asymmetric image encryption method is …

In the age of Information Technology, the day-life required transmitting millions of images
between users. Securing these images is essential. Digital image encryption is a well-known …

To explore characteristic of a new system with fractional order and complex variables, based
on Adomian decomposition method (ADM), its nonlinear dynamical behaviors are discussed …

In traditional compressed sensing (CS), the measurement matrix always faces problems
such as large data storage, high memory usage and a large amount of data calculation. To …

Medical image encryption may help protect medical privacy. In this paper, we propose a new
medical image encryption scheme combined Latin square and chaotic system. The …
