Image Encryption Using Modified Rubik’s Cube Algorithm

For multimedia applications, data are developed and transmitted through the networks. These multimedia data should not be accessed by the unauthorized persons as it contains information. So, in current scenarios image security and privacy become a major issue in communication. In this work, we proposed an advanced encryption scheme based on modified Rubik’s cube algorithm. First, the original image is scrambled using two secret keys, which is generated using logistic function and shift register method, respectively. Then, with XOR operator, rows and columns of the scrambled image are again mixed using various means. Performance of the proposed work is assessed with correlation coefficient and information entropy. From the experimental analysis and security parameter evaluation, it can be observed that the proposed scheme can resist exhaustive attack, statistical attack and differential attack.
