摘要：

In this paper, we propose to enhance a recently proposed image cryptosystem based on hyper-chaos. The updated version has been builded to resist against attacks made to break the original one and to make it faster. The modification concerns the two Boxes, P-Box and S-Box, which composed the original cryptosystem. Compared with classical encryption schemes, AES and Triple-DES, the new version of the cipher shows a better performances in rapidity, in confusion and in the key sensitivity.
