Abstract

This paper proposes a new sine-multi dynamic multiple coupling mapping lattice (SMDMCML). Through comprehensive analysis, the SMDMCML system enhances the behavior of spatiotemporal dynamics and is more stable on the whole. Moreover, the states of lattices in SMDMCML are more chaotic than the coupled map lattice (CML) or even the multiple coupled mapping lattices (MCML) models. Therefore, a new two-way independent diffusion in color image encryption algorithm is proposed based on SMDMCML. Through simulation experiments analysis, R, G, and B components have lower correlation and higher sensitivity. This further proves that SMDMCML system has good chaotic performance and conforms to characteristics of cryptography.
