In order to improve security and encryption performance of the color image information

and at the same time high-dimensional chaotic system with higher security

a new color image encryption algorithm is proposed based on a hybrid chaotic system of multi-channel parallel. The color image decomposed into

and of monochrome images

the three monochrome images using different high-dimensional chaotic system chaotic sequence

using three different structure chaotic encryption scrambling pixel position and the pixel value several rounds of proliferation

so as to realize image encryption. The component image used Lorenz chaotic system; component image used Ressler chaotic system; component image used Chen chaotic system. Simulation results show that the algorithm not only has a sufficiently large key space

but also has a good effect and high security encryption and encryption performance.
