摘　　要：借助可信中心的协助,引入用户身份验证和密钥验证机制,提出一种适用于电力通信系统的树型网络可验证多方量子密钥分配协议。利用带密钥的单向hash函数技术同时对每个用户进行身份验证和密钥验证,保证两者可以在同一个步骤中完成。发送者和接收者之间无需进行公开讨论,节省了资源,降低了成本。和其他利用纠缠资源的协议相比,该协议采用单光子作为量子信息载体,且单光子不需要存储,在技术上更容易实现。通过对该协议进行安全性分析,表明该协议在理论上是安全的。With the help of Trust Center,we introduced user authentication and key authentication mechanism,and proposed a verifiable multi-party quantum key distribution protocol based on tree network for power communication system.Using one-way hash function with key to simultaneously authenticate and verify each user ensured that both can be completed in the same step.There is no need for open discussion between sender and receiver,saving resources and reducing costs.Compared with other protocols using entanglement resources,this protocol used single photon as quantum information carrier,and single photon did not need to be stored,so it was easier to implement technically.The security analysis of the protocol shows that the protocol is theoretically secure.
