| Abstract: | This paper proposes an algorithm to realize the image encryption with 1-D piece-wise chaotic symbol dynamics.Based on the principle of chaotic symbol dynamics,the position and the value of each pixel are scrambled by different chaotic sequence,which are gotten from only one short chaotic sequence.To realize the image encryption,the encryption algorithm uses the chaotic sequence to determine the algorithm of interchanging the rows,uses the primary matrix which is determined by the different chaotic sequence ... |
