Abstract :
An improved image encryption algorithm based on chaos is proposed for the degradation of periodicity, in which permutation is firstly carried out. Then the permuted image is encrypted by Chen´s chaotic system pixel by pixel and it makes the encryption more secure because the dynamical property of the Chen´s chaotic system is more complicated than the Lorenz chaotic system. The experiment results demonstrate that the presented algorithm improves the histogram distribution of the image.
