A New Image Encryption Algorithm Based on Arnold and Coupled Chaos Maps
At the basis of using Arnold to replace pixel, this algorithm draw into Logistic map to generate a chaotic sequence, which is used as the Henon map parameters and the number of iterations, then through the chain iteration of Henon map and XOR to encrypt the grey value. After that, the image pixel value is uniform distributed. The test practice and performance analysis shows that, this algorithm has good spreading and can be effective against exhaustive key search attack and attacks on phasespace reconstruction. So it has a good safety and reliability.
