摘　　要：在配网运行场景下,终端分布点多面广,部分业务将通过无线通信或公网承载,网络开放性增强,安全风险加剧。量子密码技术的应用能够极大提高通信通道的安全性,但在海量终端接入等方面仍存在实用化挑战。针对这一问题,文章研究了轻量级、低成本的量子密码技术应用体系架构,可通过量子边缘节点实现海量无线终端的灵活便捷接入,并在此基础上探讨了该方案在典型配网运行业务场景的应用前景。In the distribution network operation scenario,terminals are widely distributed,and some services will be carried through wireless communication or public networks.The network openness is enhanced,and security risks are intensified.The application of quantum cryptography can greatly improve the security of communication channels,but there are still practical challenges in terms of massive terminal access.To solve this problem,this paper studies the application architecture of lightweight and low-cost quantum cryptography technology,which can realize flexible and convenient access to mass wireless terminals through quantum edge nodes.On this basis,the application prospect of this scheme in typical distribution network operation business scenarios is discussed.
