| 摘要: |
| 基于Einistein-Podolsky-Rosen纠缠对与量子安全直接通信(QSDC)，提出了一个新的基于Bell态的量子对话协议。通信双方Alice和Bob只需要进行一次通信即可实现双方之间秘密的同时交换。该方案利用一个随机比特串和检测光子来实现安全性，能够抵抗截获/重放攻击、特洛伊木马攻击和纠缠攻击等典型攻击。很多近期提出的协议中存在严重的信息泄漏，也就是说任何窃听者都可以从合法通信者的公开声明中提取到部分秘密信息，我们的方案很好地克服了这一问题。协议的效率较高，可以达到66.7%，同时由于纠缠态粒子只需要进行一次传输，该方案更简单易行。将该协议推广到two-qutrit态，其安全性仍能得到保证。 |

| Abstract: |
| Drawing on the idea of the quantum secure direct communication (QSDC), a novel quantum dialogue scheme based on Bell states is presented in this paper. The proposed scheme can realize authorized parties’ secure exchange of their respective secret messages simultaneously only through one communication. In this scheme, a random bit string and checking particles are used to ensure the security; the scheme is secure against eavesdropper's commonly used attacks, such as intercept/resend attack, Trojan horse attack and entanglement attack. A serious problem called “information leakage” or “classical correlation” is found in some quantum dialogue protocols, namely, any eavesdropper can elicit some information about the secret from the classical communication of the legal users. Fortunately, our protocol can discard the drawback “information leakage”. In addition, our protocol possesses high efficiency 66.7% and is feasible. Finally, the protocol is applied to the scheme based on two-qutrit entangled states with a secure communication. |
