Recently, a novel bit-level color image encryption scheme based on improved one-dimension (1D) chaotic map has been proposed. It was claimed that the proposed scheme is secure due to the improved 1D chaotic map with better chaotic performance. Some security analyses and simulation experiments were presented to show that it could resist various attacks. However, we found that there are some security loopholes in the original scheme, and then proposed an effective attack strategy utilizing chosen-plaintext attack (CPA) in this paper. The proposed strategy mainly includes two attacks. The first is to obtain the equivalent secret key of the diffusion right shift phase, and the second is to obtain the permutation right shift rule. The effectiveness and feasibility of the proposed method are verified by both theoretical analyses and experimental results. Some proposals are also given for improving the security of the original encryption scheme.
