| Abstract: | A chaotic color image encryption algorithm is proposed on the basis of properties of chaotic sequences.At first,the chaotic sequences are generated by dealing with Logistic and Cubic-Henon compound chaotic system.Then the color image is encrypted by combining the methods of pixel value substituting and position shuffling.The results of simulation experiment and performance analysis show that the algorithm is valid and has good performance. |
