A color image encrypting algorithm based on multiple chaotic systems
Liu Li · 2013
In order to effectively improve the color image encryption effect,a digital color image encryption algorithm is designed based on chaotic system.At first,arnold mapping is applied to the scrambling operation on the pixel position matrix of the red,green and blue(R,G,B)components of the color image.Based on this,Logistic and Henon mappings are used to generate chaotic sequence with the processed images R,G,B color component parity pixels exclusive OR to achieve a color image encryption.The simulation results show that chaos replacement operation based on multiple chaotic system set color image with different base color completely confused,and therefore obtain a preferable encrypted effect and better security.
