Summary:A novel iterative image encryption scheme using the image dyadic displacement, the linear feedback shift registers and discrete wavelet transform is proposed to defeat the disadvantages of the conventional image encryption using the dyadic displacement. Multi-keys are used in the proposed scheme to promote the security level of the image encryption, furthermore. The results of the simulations show that the decrypted image is a noise and hardly to be identified if any key used in the decryption process is wrong.
