基于QKD的组密钥服务初始化研究

Research of Group Key Service Initialization Based on QKD

随着量子密码学领域研究的深入,视频会议、网络游戏、股市交易等动态群组通信模型对量子组密钥提出了应用需求。为了很好地服务这类应用,在分析传统组密钥管理方案的基础上,给出了一种两层分组分布式量子组密钥管理模型,设计了这种模型下的量子组密钥服务协议,重点研究了协议的初始化阶段。与几种经典组密钥管理方案对比,该方案在组密钥生成和共享中效率较高,具有一定的实际意义。

With the deepening of the quantum cryptography field research, video conference, networks games, stock trading and other dynamic group communication models put forward application requirements to quantum group key. In order to service these applications well,on the basis of analyzing the traditional group key manage-ment scheme, present a two layers of packet distributed quantum group key management model, design the quan-tum group key service agreement under this model, focus on the initialization phase of the agreement. Compared with several kinds of classic group key management scheme, this scheme＇s efficiency is higher in group key gen-eration and sharing, has certain practical significance.
