Thirdly, Instead of using one-dimensional coupled map lattices model, we have constructed a combinable model, which is consisted of an one-dimensional chain, a two-dimensional netting grid and another one-dimensional chain as the drive-response system. So both the system's complexity for secret key streams and the efficiency for encryption have been increased.
