量子安全直接通信是量子密码学的一个重要分支,它通过量子信道直接发送秘密信息而无需预先设置密钥。在过去的十年中,已经提出了许多协议,其中一些已经通过实验证明。双向协议被认为是最实用的协议之一,在本文中,我们给出了双向量子安全直接通信协议在考虑噪声和有损信道时的安全性证明。
Quantum secure direct communication is one of the major branches of quantum cryptography, which sends secret information through a quantum channel directly without setting up a prior key. Over the past decade, numerous protocols have been proposed, and some of them have been experimentally demonstrated. The two-way protocol is seen as one of the most practical protocol; in this paper, we present the security proof of the two-way quantum secure direct communication protocol when the noisy and lossy channel is taken into account.
