Jianbing Shen · Jisuanji gongcheng · 2002
In this paper, a new method for digital image scrambling transformation, namely Magic Cube Transformation, is proposed. Combined with the Logistic mapping in non-linear dynamics system, an image encrypting and decrypting algorithm based on Magic Cube Transformation is designed. Firstly, a natural chaotic sequence is created with the key. With this chaotic sequence, the image matrix is transformed to an encrypted image by Magic Cube Transformation. The decrypting operation is the reverse process of encryption. The results indicate that the proposed algorithm can get satisfying effect. Finally, the characteristics of the algorithm are summarized and the aspects of the subsequent work are prospected.
