Image array disturbed algorithm has been improved to implement multiple permute better.The algorithm shortens its encryption time, so it fits image encryption well.
With the change of control parameters,typical variation of physical state is studied to extend the applications of chaus circuits chaotic systems in Chais circuits.
It is difficult to achieve the synchronization for the master-slave chaotic systems with nonidentical parameters,so the uniform synchronization with a small error bound is discussed.
So I suggested that find the way to resolve the puzzle of earthquakeprediction by chaos theory on the basis of the mass of the data in the earthquake observingstation.
