a new image block encryption integrating algorithm based on four-dimensional hyperchaotic system and neural network mechanism is cnstructed. Firstly, a hyperchaotic system is proposed, which combines with cloud model, meanwhile generates a series with better randomness as key stream. Then key stream, neural network mechanism and Feistel block strueture are combined to encryption the image. Finally, the experimental results show that the algorithm has good security.
