A novel controlled flexible representation for quantum image(CFRQI) is firstly proposed in this paper based on flexible representation for quantum image (FRQI). The proposed CFRQI is able to effectively help the sender control the whole process of information transmission for better information security. Next, a novel secure controlled quantum image steganography algorithm is proposed by making full use of controlled access mechanism that comes with CFRQI. Compared with the previous quantum steganography algorithms, the new algorithm can make the sender control whether the receiver is enabled to correctly receive secret information or not for better imperceptibility. And it also can achieve better security by introducing the controlled access mechanism as an identity authentication system without the need of auxiliary information. Good applicability of the new algorithm is proved by the quantum circuits of embedding and extracting processes that are designed to implement. Furthermore, the new algorithm can effectively resist the phase-damping and amplitude-damping noises in quantum channel through theoretical analysis. Finally, the simulation experiment results are presented to prove our conclusions.

一种安全控制的量子图像隐写算法

基于量子图像的柔性表示(FRQI),本文首次提出了一种新颖的量子图像的控制柔性表示(CFRQI)。提出的CFRQI能够有效地帮助发送方控制信息传输的整个过程,从而提高信息安全性。接下来,通过充分利用CFRQI附带的受控访问机制,提出了一种新颖的安全受控量子图像隐写算法。与以前的量子隐写术算法相比,新算法可以使发送方控制接收方是否能够正确接收机密信息,以更好地感知。并且,通过引入受控访问机制作为身份认证系统,无需辅助信息,也可以实现更好的安全性。通过设计实现的嵌入和提取过程的量子电路,证明了该新算法的良好适用性。此外,通过理论分析,新算法可以有效地抵抗量子信道中的相位衰减和振幅衰减噪声。最后,给出了仿真实验结果以证明我们的结论。
