A novel color image encryption approach based on multi-chaotic system

The paper presents an image encryption algorithm that combines logistic map and Chen map. A traversal integer pseudorandom sequence that is generated by logistic map is used for shuffling bit-plane, rows and columns of plain image. A chaotic matrix of which is generated by Chen map is stacked to the shuffled image to form encrypted image. Experiment results show that it has good performance of resisting all kinds of known attacks.
