论文摘要
根据GHz状态的密集编码和纠缠交换，提出了具有大量有效载荷的量子隐志协议。它的超级量子通道是通过在原始量子安全直接通信（QSDC）方案中建立隐藏通道来形成的。根据原始的QSDC，通过整合GHz状态的密集编码和GHz州的纠缠交换来传输秘密消息。它的超级量子通道的能力每回合秘密通信达到六位位，远高于以前的量子隐志协议。它的不可识别是很好的，因为信息和秘密消息可以被认为是随机的或伪随机的。此外，事实证明其安全性是可靠的。
A quantum steganography protocol with large payload is proposed, based on dense coding and entanglement swapping of GHZ states. Its super quantum channel is formed by building up the hidden channel within the original quantum secure direct communication (QSDC) scheme. Based on the original QSDC, secrets messages are transmitted by integrating dense coding of GHZ states and entanglement swapping of GHZ states. Its capacity of super quantum channel achieves six bits per round covert communication, much higher than the previous quantum steganography protocols. Its imperceptibility is good, since the information and secrets messages can be regarded to be random or pseudo-random. Moreover, its security is proved to be reliable.
