摘要:

针对现有基于密钥中继的 QKD 网络路由方案存在适用范围有限、不能满足广域环境路由需求的问题,分析了广域 QKD 网络路由特点并提出了相应的路由需求,进而设计了基于虚链路的分域量子密钥网络路由方案。将广域 QKD 网络划分为多个小规模的密钥路由域,降低了域内密钥路由的复杂度,通过建立跨越密钥路由域的虚链路缩短了域间路由长度,从而提高了广域环境下密钥路由效率。理论分析表明,该方案具有路由更新收敛快、路由时延小、密钥资源消耗少的优点。

Abstract:

The existing routing schemes for key relaying QKD network had a limited scope of application and could not satisfy the requirements of the routing issue of wide-area QKD network.A multi-domain routing scheme based on visual link was proposed for QKD network after the analyzing of the characteristics of QKD network and the proposing of the design requirements of routing issue.In this routing scheme,the QKD network was divided into multiple routing areas to reduce the complexity of intra-domain routing,and a visual QKD link striding over the whole key routing area was built to shorten the routing path.Therefore,the routing efficiency can be increased by this scheme.After theoretical analysis,the proposed routing scheme has advantages of fast convergence of routing update,little time delay and low key material cost.

Key words: quantum key distribution, wide-area QKD network, key relaying, routing scheme
