Image-encrypted Algorithm Based on 3D Baker Mapping and Complicated Chaotic Sequence
Geng Chen · Journal of Shandong University of Science and Technology · 2008
An image-encrypted algorithm based on 3D Baker mapping and complicated chaotic sequence is proposed.The encrypted algorithm processes the color values of each image point and the array of original image based on three kinds of chaotic sequences,i.e.the 1D infinite collapse mapping and the 2D Henon mapping and the 1D Logistic mapping.The service sequence of the two scrambling algorithm will be decided by a judicative condition,and this method is better than that using the same chaotic system with the chaos many times.The simulation results show that the encrypted algorithm has good efficiency and high security.
