| Abstract: | Some parameters to value the image encryption algorithm based on chaotic system are advanced in the paper.Using these parameters,we make analysis and evaluation for a typical image encryption algorithm through simulative test.The results indicate that they are so practical and effective as to across-the-aboavd evaluate scrambling criterion and the safety of image scrambling algorithm based on chaotic system. |
