%X A new scheme of scrambling digital image is proposed in this paper.Its concepts and models are described in detail.The scheme is based on matching pairs of the image matrix and shift operator.The discrete Chebyshev mapping is employed to generate secret key chaotic streams as scrambling parameters.With the properties of chaotic system,the proposed algorithm has the features of randomness as well as varieties for image scrambling.At last,the problem for security is discussed,and the test result is obtained efficiently.
