目前，人们提出了与量子密钥分发协议不同的量子秘密通信算法，称为量子安全直接通信协议。这些的目的并不是在两个通信者之间达成密钥协议，而是直接使用量子设备发送秘密消息。在本文中，我们提出了一种新的量子秘密直接通信协议，该协议比现有协议具有优势，并讨论了其针对中间人攻击的安全性分析。
These days, quantum secret communication algorithms different from quantum key distribution protocol have been proposed, which are called quantum secure direct communication protocols. These do not aim to have a key agreement between two communicators, but, to send a secret message directly using quantum devices. In this paper, we propose a new quantum secret direct communication protocol which has advantages over the current ones and also discuss its security analysis against the man-in-the-middle attack.
