Image encryption using 3D Logistic-Sine cascade map

open access: yesDianzi Jishu Yingyong, 2020
This paper proposes a three-dimensional Logistic-Sine cascade map(3D-LSCM). Firstly, a three-dimensional Logistic-Sine cascade map was constructed by using the output of the Logistic map as the input of the Sine map.

Route to chaos in generalized logistic map [PDF]

open access: yes, 2015
Motivated by a possibility to optimize modelling of the population evolution we postulate a generalization of the well-know logistic map. Generalized difference equation reads: \begin{equation} x_{n+1}=rx^p_n(1-x^q_n), \end{equation} $x\in[0,1],\;(p,q)>0,

A q-deformed nonlinear map [PDF]

open access: yes, 2004
A scheme of q-deformation of nonlinear maps is introduced. As a specific example, a q-deformation procedure related to the Tsallis q-exponential function is applied to the logistic map.

Visualizing the logistic map with a microcontroller [PDF]

open access: yes, 2011
The logistic map is one of the simplest nonlinear dynamical systems that clearly exhibit the route to chaos. In this paper, we explored the evolution of the logistic map using an open-source microcontroller connected to an array of light emitting diodes (

Deciphering a novel image cipher based on mixed transformed Logistic maps [PDF]

open access: yes, 2015
Since John von Neumann suggested utilizing Logistic map as a random number generator in 1947, a great number of encryption schemes based on Logistic map and/or its variants have been proposed. This paper re-evaluates the security of an image cipher based
