摘　　要：利用NEQR量子图像表示法,提出了一种能在含水印量子载体图像中实现隐蔽通信的量子隐写算法。新算法借助水印通常拥有很好的稳健性和其特有的自恢复系统,对秘密信息的稳健性进行了多重强化。相比于之前的量子隐写算法,新算法不仅强化了秘密信息自身的稳健性,而且通过量子线路的设计提高了其嵌入和提取的可执行性和执行效率。经实验仿真结果和性能分析验证,新算法在保留原有隐蔽性和安全性基础上,进一步提高了秘密信息的稳健性和嵌入率。Based on the novel enhanced quantum representation（NEQR） , this paper proposed a new quantum steganography algorithm to realize the covert communication by using the quantum carrier image with the watermarking. The new algorithm was enhanced on the basis of the good robustness of the watermarking and the unique self-recovery system. Compared with the previous quantum steganography algorithms, the new algorithm not only enhanced the robustness of the embedded secret information, but also improved the performability and efficiency. Through experimental results and the performance analysis verification, the new algorithm further improves the robustness and embedding rate of the secret information on the basis of retaining the original imperceptibility and security.
