Image encryption using 3D Logistic-Sine cascade map
Dianzi 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.

On the Complex and Chaotic Dynamics of Standard Logistic Sine Square Map
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2021 In this article, we set up a new nonlinear dynamical system which is derived by combining logistic map and sine square map in Mann orbit (a two step feedback process) for ameliorating the stability performance of chaotic system and name it Standard ...

Speech encryption algorithm based on two newly designed chaotic maps
Franklin Open, 2023 Two new integrated chaotic maps are designed. The sine and logistic maps are used to create a sine-logistic integrated map (SLIM). The sine and cubic maps are used to design a sine-cubic integrated map (SCIM). Their dynamical analyses are done using time

Finite size effects and the supersymmetric sine-Gordon models [PDF]
, 2003 We propose nonlinear integral equations to describe the groundstate energy of the fractional supersymmetric sine-Gordon models. The equations encompass the N = 1 supersymmetric sine-Gordon model as well as the phi(id,id,adj) perturbation of the SU(2)(L ...

Color Image Encryption Using 2D Sine-Cosine Coupling Map
IEEE Access, 2022 In this paper, a new two-dimensional sine-cosine coupling chaos map(2D-SCCM) is proposed. The performance of the proposed two-dimensional chaotic system is analysed by using trajectory distribution maps, Lyapunov exponents, sample entropy and sequence ...
