摘　　要：提出了一种利用可信控制中心以及可信量子中继服务器进行量子密钥中继传输的实现方案。在设计可信中继点协议上采用了量子密钥一次一密的加密算法,在组建可信中继网络时,利用可信控制中心来保证接入中继的可信性与安全性,并把用户地址隐藏于已加密的量子信息数据中,只有合法的可信用户才能解密并进行信息传输。实验结果表明,用户之间即使没有量子信道直接相连,仍然可以利用可信中继网络进行量子密钥长距离的安全传输,该量子密钥中继方案是可行的。安全性分析表明,在传输过程中,攻击者无法获取到真正有用的量子密钥信息。A transmit quantum key relay scheme based on trusted control center and trusted quantum relay server was proposed.The quantum key one-time pad encryption algorithm was used in the design of trusted relay protocol.Upon the establishment of trusted relay network,the trusted control center was used to ensure the credibility and security of access relay,and the user＇s IP address was hidden in the quantum information data that had been encrypted only for the legal user to decrypt and transmit credible information.The security analysis shows,users who do not connect with the quantum channel can still use the trusted relay network to transmit quantum key securely in a long-distance transmission while attackers can not obtain useful quantum key information from the network.
