In the medical field, advanced techniques like e-health, smart health, and telemedicine
applications are in use. These techniques transmit a digital medical image via open-source …

Neural networks are favored by academia and industry because of their diversity of
dynamics. However, it is difficult for ring neural networks to generate complex dynamical …

In this paper, a chaotic image encryption algorithm based on the matrix semi-tensor product
(STP) with a compound secret key is designed. First, a new scrambling method is designed …

This paper presents a color image cryptosystem based on dynamic DNA encryption and
chaos. The color plain image is firstly decomposed into red, green and blue components …

Image encryption provides confidentiality to images by transforming them into
unrecognizable forms that resemble white noise. Digital chaos is one of the areas used to …

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 …

For a linear image encryption system, it is vulnerable to the chosen-plaintext attack. To
overcome the weakness and reduce the correlation among pixels of the encryption image …

In this paper, we report an effective cryptosystem aimed at securing the transmission of
medical images in an Internet of Healthcare Things (IoHT) environment. This contribution …

In this paper, a new combination chaotic system (NCCS) is proposed for image encryption.
The proposed system has larger key space and exhibits better cryptographic features in …

The security of healthcare and telemedicine systems is a critical issue that must be
significantly investigated. Several smart telemedicine applications are expected to be …
