摘要：
Recently, a parallel sub-image encryption method with high-dimensional chaos has been proposed. But there is a fatal flaw in the cryptosystem that the generated keystream remains unchanged when encrypting every image. Based on this point, we could recover the plaintext by applying chosen plaintext attack. Therefore the proposed cryptosystem is not supposed to be used in image transmission system. Experimental results show the feasibility of our attack.
