A Novel Intermittent Jumping Coupled Map Lattice Based on Multiple Chaotic Maps

Coupled Map Lattice (CML) usually serves as a pseudo-random number generator for encrypting digital images. Based on our analysis, the existing CML-based systems still suffer from problems like limited parameter space and local chaotic behavior. In this paper, we propose novel intermittent jumping CML system based multiple maps. The mechanism seeks to incorporate multi-chaos, dynamically switch coupling states relations, varying with spatiotemporal indices. Extensive numerical simulations comparative studies demonstrate that, compared systems, proposed has larger space, better behavior, comparable computational complexity. These results highlight potential of proposal deployment into an image cryptosystem.
