摘　　要：为了满足量子容量有限的客户端对大量量子计算的需求,盲量子计算应运而生,它可以实现客户端与量子计算机之间的远程交互,从而确保信息传输的安全。提出了一种新的多方认证盲量子计算,它可以回收使用预共享密钥,进而使用BQC(blindquantumcomputing)的量子密钥回收功能来提高量子资源的利用效率。在BQC协议中,有4种参与者:客户端、服务器、负载平衡器和半诚实证书颁发机构(certificateauthority,CA)。包括了2个阶段:密钥分发和盲量子计算。在第1阶段,负载平衡器在证书颁发机构的帮助下完成身份验证和密钥分发,并回收可再次用于协议的下一个新实例的密钥。在第2阶段,盲量子计算使客户端能够仅通过测量来自服务器的量子比特来完成计算任务,而无须准备量子比特。客户端可以使用服务器来测量以完成计算。与传统的BQC协议相比,提出的量子密钥回收协议可以大大提高密钥分发和重用的效率,在论文的效率分析部分对此进行了证明。In order to fulfill the requirements of the client with limited quantum capacity for a large number of quantum computing,blind quantum computing(BQC)emerged as the times require,which can realize the remote interaction between the client and the quantum computer and ensure the security of information transmission.In this paper,we propose a new multi-party authentication blind quantum computation,which can recycle the used pre-shared keys.And then we use the quantum key recycling function of BQC to improve the utilization efficiency of quantum resources.In our BQC protocol,there are four kinds of participants:client,server,Load_Balancer and semi-honest certificate authority(CA),which consists of two stages:key distribution and blind quantum computing.In the first stage,the Load_Balancer completes identity authentication and secret key distribution with the help of the certificate authority,and recycles the secret keys that can be used again for next new instance of the protocol.In the second stage,blind quantum computing enables the client to complete the computing task only by measuring the quantum bits from the server without preparing the quantum bits.The client can use the server to measure the quantum to complete the computation.Compared with the traditional BQC protocol,our proposed quantum key recycling protocol can greatly improve the efficiency of key distribution and reuse,we prove it in the efficiency analysis part of the paper.
