摘要：To improve image encryption mechanism and enhance the security of pixel value transformation, a new image encryption scheme is proposed based on quantum chaos. In the phase of key generation, running key related to plaintext is generated by cipher-text successively disturbing chaotic component. In the process of encryption, polynomial multiplication in Galois field is first introduced to perform pixel encryption and then the cipher-text is encrypted again with cipher-text feedback mechanism. The experiment results show that the introduction of disturbing mechanism implements one time running-key stream, minimization of dynamical degradation of digital chaos, and resistance to reconstruction attack. In addition, polynomial multiplication which is first applied in the encryption system degrades the possibility of breaking our scheme in theory. Finally, some analyses such as correlation, sensitivity, min-entropy, and time complexity further demonstrate the security and efficiency of our scheme.
