摘要:近年来,随着网络通信攻击手段的层出不穷,只依赖传统计算困难程度的密钥分发
的安全性受到了严重威胁。量子密钥分发技术由于其无条件安全性的优势,与光网络结合,在信
息的保密性和传递效率方面具有突出的表现。利用量子密钥分发技术组建的量子密钥分发网络
也在全球范围内得到逐步应用并且不断发展。重点总结了量子密钥分发各项协议及量子密钥分
发网络的发展历程,以量子密钥分发网络所面临的生存性和连通性,以及中继节点的布置问题为
切入点,分析了量子密钥分发网络目前存在的不足及现有的各种解决方案。最后,从实际的角度
出发,分析和总结了量子密钥分发网络的应用现状,通过量子密钥分发在线与离线相结合的方式,
使量子密钥分发网络的可推广性变得更强,同时,边缘网关到物联网终端设备的量子密钥分发也
大大促进了量子密钥分发网络与现有物联网设备的结合应用。
