Abstract: With the rapid growth in usage of multimedia images and digital data exchange, it is very important to safeguard the images from unauthorised access. In this context, we proposed a multi-level chaotic encryption scheme using modified Rubik's cube algorithm. First, the original image is jumbled using two secret keys. These keys are generated using chaotic functions with different parameters. Then rows and columns of the jumbled image are again mixed with XOR operator. Performance of the proposed work is evaluated with correlation coefficient (CC), number of pixel change rate (NPCR) and unified average changing intensity (UACI). From the experimental analysis and parameters evaluation it is observed that the proposed scheme can resist exhaustive attack, statistical attack as well as differential attack.
