摘要 针对量子通信网络构建成本昂贵且效率低下的问题,基于贝尔态粒子和半量子理论,提出了一种易于实现的量子安全直接通信模型。首先,量子态的制备、Bell基测量等复杂操作交由拥有全部量子能力的服务端完成,用户端只需完成投影测量或者直接反射两种简单操作;其次,通信双方传输秘密信息前建立量子信道并提前共享安全密钥,可以严格保障秘密信息不被泄露;最后,通过设计的编码规则,使得协议只使用较少量子资源就完成高效的秘密信息直接传输。通过计算可得,提出的量子安全直接通信模型粒子传输效率达到7.69%,安全模型分析表明了提出的通信模型在各种常见的攻击策略下都是安全可靠的。

英文摘要 Aiming at the costly and inefficient problem of quantum communication network construction, based on the Bell state particle and semi-quantum theory, this paper proposed an easy-to-implement quantum safety direct communication model. Firstly, it performed the preparation of quantum states, such as Bell-based measurements, by a server with all quantum capabilities. The user only needed to perform two simple operations: projection measurement or direct reflection. Secondly, the quantum channel established before the communication parties transmit the secret information and the security key shared in advance could strictly guarantee that the secret information was not leaked. Finally, through the design of the coding rules, the protocol used only a small amount of quantum resources to complete efficient transmission of secret information. Through calculation, the proposed quantum security direct communication model has a particle transmission efficiency of 7.69%. The security model analysis shows that the proposed communication model is safe and reliable under various common attack strategies.
