In this paper, we construct a semi-quantum dialogue (SQD) protocol by using Bell entangled states as the initial quantum resource. The information leakage problem is prevented by utilizing the entanglement correlation of two particles from one Bell entangled state. The security towards active attacks from an outside Eve is guaranteed by twice security checks and one classical one-time pad encryption process. The proposed SQD protocol can be realized in experiment with present quantum technologies. Compared with the traditional quantum dialogue (QD) protocols without information leakage, the advantage of the proposed SQD protocol lies in that it doesn’t require both communicants to possess quantum capabilities.

与贝尔纠缠态的半量子对话

在本文中，我们通过使用贝尔纠缠态作为初始量子资源构建了一个半量子对话（SQD）协议。通过利用来自一个贝尔纠缠态的两个粒子的纠缠相关性来防止信息泄漏问题。对来自外部 Eve 的主动攻击的安全性由两次安全检查和一次经典的一次性加密过程保证。所提出的 SQD 协议可以在现有量子技术的实验中实现。与没有信息泄漏的传统量子对话（QD）协议相比，所提出的SQD协议的优势在于它不需要通信双方都拥有量子能力。
