...not good for image data either for a low encryption eciency [39] or a relatively small block size for encryption. Many image ciphers have been researced, including chaotic system based image ciphers [7, 10, 13, 15, 18, 19, 23, 25, 27, 35, 36, 41, 42], SCAN language based algorithms [11, 12], transform based algorithms [24, 31, 38] and others [22]. On the other hand, the distinctive characteristics of image data implies that the randomness tests d...

...It is well known that a good encryption algorithm should be sensitive to the cipher keys, and the key space should be large enough to make brute-force attacks infeasible [12]....
