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 …

With complex properties of ergodicity, unpredictability and sensitivity to initial states, chaotic
systems are widely used in cryptography. This paper proposes a two-dimensional Logistic …

Because of the excellent properties of unpredictability, ergodicity and sensitivity to their
parameters and initial values, chaotic maps are widely used in security applications. In this …

Derived from Sine map and iterative chaotic map with infinite collapse (ICMIC), a new two-
dimensional Sine ICMIC modulation map (2D-SIMM) is proposed based on a close-loop …

Chaos theory has been widely used in the design of image encryption schemes. Some low-
dimensional chaotic maps have been proved to be easily predictable because of their small …

In cryptography, chaotic cryptosystem is one of the methods to carry out encryption and
decryption of images. This paper introduces a new symmetric key encryption technique …

In this research paper, we propose a novel one-dimensional chaotic system based on the
fraction of cosine over sine (1-DFCS). Evaluation of 1-DFCS indicates the existence of a …

The operation of image filtering is widely used to deblur digital images. However, using
inappropriate masks, it can also blur images. Motivated by this concept, this paper …

In this paper, a new image encryption algorithm based on Brownian motion and new 1D
chaotic system is introduced. Firstly, SHA 256 hash value of the plain image is used to …

In this paper, we propose a new real one-dimensional cosine polynomial (1-DCP) chaotic
map. The statistical analysis of the proposed map shows that it has a simple structure, a high …
