摘　　要：量子密钥分发(quantum key distribution,简称QKD)因其具有理论上的无条件安全性而备受关注,但是在实际系统中,QKD会由于设备的非完美性而易受到量子黑客的攻击。测量设备无关(measurement device independent,简称MDI) QKD方案的提出,很好地解决了这一问题。本文首先介绍MDI-QKD协议的最新研究进展和实现原理,总结归纳了协议在实际应用中的优越性与不足,在分析MDI-QKD改进协议的基础上,重点研究提升方案安全密钥生成率的方法并进行理论证明。Quantum key distribution (QKD) has been paid much attention because of its theoretical uncondi-tional security. However, in the actual system, QKD will be vulnerable to Quantum hackers because of non-perfection of equipment. The proposal of the measurement device independent (MDI) QKD provide a good solution to this problem. In this paper, we firstly introduce the latest research progress and implementation principles of the MDI-QKD protocol. And then, we summarize the advantages and disadvantages of the protocol in the practical application. Based on the analysis of the MDI-QKD improvement protocol, our research is mainly focused on the method of lifting scheme secure key generation rate and theoretical proof.
