Based on the five order cellular neural network hyperchaotic system model, a new algorithm for image encryption is proposed. This encryption algorithm is synchronous method of active control system for the application of Hyperchaotic Chen system of five dimensional hyperchaotic cellular neural network and four two Heterodimensional heterogeneous, as long as to find a suitable nonlinear synchronization controller, the error system tends to zero, to achieve synchronization. And to the image encryption using synchronization of Hyperchaotic Chen system of five dimensional hyperchaotic cellular neural network and four, from the encryption result we can see that the encryption algorithm has good encryption effect.
