摘要

This paper proposes a novel Pixel-Chaotic-Shuffle method for image encryption. Since the dynamic response of chaotic system is highly sensitive to the initial values of a system and to the variation of a parameter, chaotic trajectory is very unpredictable. Therefore we use the chaotic sequences generated by chaotic systems as encryption codes and then implement the digital-color image encryption with high security. The proposed method combined with 4 chaotic systems and pixel shuffle can fully banish the outlines of the original image, disorders the distributive characteristics of RGB levels, and dramatically decreases the probability of exhaustive attacks. Eventually, the statistic methods involving FIPS PUB 140-1, the correlation coefficient r, NPCR (Number of Pixel Change Rate), and UACI (Unified Average Changing Intensity) are applied to test on the security analysis and the distribution of distinguished elements of variables of the encrypted image. An empirical example shows that the proposed method has the great encryption performance and achieves the high security.
