提出了一种基于布朗纠缠态的量子隐写协议。新协议充分利用纠缠态的特性，采用CNOT运算实现秘密信息的传输。与以往的量子隐写算法相比，新协议着重研究了其对相位翻转噪声的抗噪能力，证明了其对量子噪声具有良好的安全性。此外，由于新协议具有良好的不可感知性，秘密信息在量子安全直接通信信道中的隐蔽通信不会影响正常的信息传输过程。如果在覆盖协议中传输的布朗状态数足够多，则秘密信道的不可感知性可以进一步增强。在容量方面，新协议可以通过与其他量子隐写协议的结合进一步扩展其容量。由于所提出的协议在实现秘密信息的传输时不需要经典信道的参与，因此不会造成任何额外的信息泄露，具有良好的安全性。详细的理论分析表明，新协议具有良好的不可见性、容量和安全性。
In this paper, a quantum steganography protocol based on Brown entangled states is proposed. The new protocol adopts the CNOT operation to achieve the transmission of secret information by the best use of the characteristics of entangled states. Comparing with the previous quantum steganography algorithms, the new protocol focuses on its anti-noise capability for phase-flip noises, which proved its good security resisting on quantum noise. Furthermore, the covert communication of secret information in the quantum secure direct communication channel would not affect the normal information transmission process due to the new protocol's good imperceptibility. If the number of Brown states transmitted in cover protocol is many enough, the imperceptibility of the secret channel can be further enhanced. In aspect of capacity, the new protocol can further expand its capacity by combining with other quantum steganography protocols. Because the proposed protocol does not require the participation of the classic channel when it implements the transmission of secret information, it does not cause any additional information leakage and has good security. The detailed theoretical analysis shows the conclusions that the new protocol has good performance on imperceptibility, capacity and security.
