摘要:

不可信节点网络是量子互联网发展的关键一步,它最初是通过与测量设备无关的量子密钥分发(MDI-QKD)协议实现的。考虑到可信节点网络的广泛QKD实现,需要明确现有网络向MDI网络的可行升级策略。在这里,参考5G的非独立(NSA)网络,我们提出了一种NSA-MDI方案,作为现有相位编码BB84网络的演进选择。我们的解决方案可以将采用各种相位编码方案的BB84网络和终端升级为立即支持MDI,而无需更改硬件。这种具有成本效益的升级有效地促进了MDI网络的部署,作为不可信节点网络的一个步骤,同时充分利用现有网络。满足了用户对安全和带宽的多样化需求,提高了网络的生存性。

英文摘要:

Untrusted node networks initially implemented by measurement-device-independent quantum key distribution (MDI-QKD) protocol are a crucial step on the roadmap of the quantum Internet. Considering extensive QKD implementations of trusted node networks, a workable upgrading tactic of existing networks toward MDI networks needs to be explicit. Here, referring to the nonstandalone (NSA) network of 5G, we propose an NSA-MDI scheme as an evolutionary selection for existing phase-encoding BB84 networks. Our solution can upgrade the BB84 networks and terminals that employ various phase-encoding schemes to immediately support MDI without hardware changes. This cost-effective upgrade effectively promotes the deployment of MDI networks as a step of untrusted node networks while taking full advantage of existing networks. In addition, the diversified demands on security and bandwidth are satisfied, and network survivability is improved.
