许多经过认证的量子对话协议正在涌现。他们中的许多人都有信息泄露的问题，或者遭受中间人攻击。有些协议可以保证安全性，但效率相对较低。基于上述情况，我们提出了一种利用贝尔态和纠缠交换的新型认证量子对话协议。在该协议中，我们采用Einstein - Podolsky - Rosen （EPR）对来检测窃听和传输秘密信息。我们使用偏振光子来实现用户身份信息的认证。与其他带认证的量子对话方案相比，我们的协议具有以下优点。被传输的粒子只经过一次，不携带任何秘密信息。该协议克服了信息泄露的缺点，能够抵御典型的攻击。效率是可以接受的。
A lot of authenticated quantum dialogue protocols are springing up. Many of them have the problem of information leakage, or suffer from Man‐In‐The‐Middle attack. Some protocols can guarantee security, but have relatively low efficiency. Based on the above situation, we present a novel authenticated quantum dialogue protocol by using Bell states and entanglement swapping. In this protocol, we adopt Einstein‐Podolsky‐Rosen (EPR) pairs to detect eavesdropping and transmit secret messages. We employ polarized photons to achieve authentication of users' identity information. Compared with other quantum dialogue schemes with authentication, our protocol has several advantages. The transmitted particles are passed once and do not carry any secret messages. The proposed protocol can overcome the drawback of information leakage and resist against typical attacks. The efficiency is acceptable.
