| Abstract: | An image encryption algorithm based on double chaotic map is proposed. Chebyshev map and Logistic map cooperate to generate the scrambling position matrix and the pixel matrix, and the algorithm is achieved by the pixel position permutation and pixel value scrambling for two rounds. Simulation results show that the algorithm is good at encryption effect as well as robustness against common attack such as brute -force attack, statistical attack, known - plaintext attack, chosen - plaintext attack and differential attack. |
