There have been many applications of Hilbert curve such as image processing. This paper presents a new scrambling algorithm based on 3-D Hilbert curve. This algorithm extends basic Hilbert cells and uses them for scrambling. Another sorting method mixed with basic Hilbert cells algorithm is discussed to make the algorithm more effective.
