A color image encryption based on four dimensional differential equations and Arnold map (AM). High dimensional cryptosystem are increased the complexity of the encryption procedure. Initially, the four dimensional equations are used for key generation and this equation increases the range of the chaotic random values. These equations are based on the low dimensional differential equation. Secondly, the diffusion process is used for the diffuse the pixel values of the plain image. At last the AM is used for mixed or shuffle the image pixels and it is used with the parameter. Finally, the encrypted R, G and B cannel is obtained. Experimental and simulation results show that the encryption algorithm is crack the adjacent correlation between the image pixels and increase the security of the image.
