Image encryption using 3D Logistic-Sine cascade map

Abstract

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. Secondly，this paper designs an image encryption scheme using 3D-LSCM, which consists of two rounds of scrambling and two-way diffusion，and introduces the plaintext as part of initial conditions of 3D-LSCM to enchance the difficulty in deciphering equivalent keys. The feasibility of the algorithm was confirmed throung security analysis and numerical simulation.
