In this paper,a new image encryption algorithm based on Sprott-O chaos mapping and Arnold transformation is proposed,which uses Sprott-O mapping to generate stochastic sequence with the technique of image rotation,Arnold scrambling and pixel replacement,finally the encrypted image is obtained. It's a simple and efficient algorithm with low computational complexity and high safety by theoretical analysis and simulation ,the experimental results show this algorithm has highly sensitive key and much more safer than the encryption method of image scrambling.
