  • 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.
