Parallel Multi-channel Color Image Encryption Based on Hybrid Chaotic System

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 R, G, and B 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 R component image used Lorenz chaotic system; G component image used Ressler chaotic system; B 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.
