Yonghong Zhang · Journal of Engineering Design · 2008
An algorithm to construct extended chaotic sequence was proposed and this sequence was applied in encryption of digital image.Two methods based on n-degree Bezier curve and n-degree rational Bezier curve to construct extended chaotic sequence were put forward,the constructed chaotic sequence had well pseudo-randomization.Through non-linear discretization treatment,corresponding integer pseudo-random sequence could be constructed,which would be utilized to encrypt digital image.Numerical experiments show that the chaotic sequence constructed by this algorithm has good encrypting effect on digital image,and this algorithm is simple and highly secure.
