Magic cube encryption for digital image using chaotic sequence

The method of creating chaotic sequence using logistic mapping in non\|linear dynamics systems is introduced. A new method for digital image scrambling transformation, namely Magic Cube Transformation, is proposed. An image encrypting and decrypting algorithm based on Magic Cube Transformation is designed. Firstly, a natural chaotic sequence is created with logistic mapping. The image matrix is transformed with this chaotic sequence, using the Magic Cube Transformation. Then an encrypted image is obtained. The reverse process of encryption is the decrypting algorithm. The experimental results indicate the efficiency of the method.
