Abstract

Quantum Key Distribution (QKD) holds the promise of a secure exchange of cryptographic material between applications that have access to the same network of QKD nodes, interconnected through fiber optic or satellite links. Worldwide several such networks are being deployed at a metropolitan level, where edge computing is already offered by the telco operators to customers as a viable alternative to both cloud and on-premise hosting of computational resources. In this paper, we investigate the implications of enabling QKD for edge-native applications from a practical perspective of resource allocation in the QKD network and the edge infrastructure. Specifically, we consider the dichotomy between aggregating all the applications on the same source–destination path vs. adopting a more flexible micro-flow approach, inspired from Software Defined Networking (SDN) concepts. Our simulation results show that there is a fundamental trade-off between the efficient use of resources and the signaling overhead, which we managed to diminish with the use of suitable hybrid solutions.

QKD 安全边缘计算中的微观与宏观流量管理分析

量子密钥分发（QKD）有望在可访问同一 QKD 节点网络（通过光纤或卫星链路互连）的应用程序之间安全交换加密材料。在全球范围内，有几个这样的网络正在大都市一级部署，电信运营商已经向客户提供边缘计算服务，作为云计算和内部计算资源托管的可行替代方案。在本文中，我们将从 QKD 网络和边缘基础设施资源分配的实际角度出发，研究启用 QKD 对边缘本地应用的影响。具体来说，我们考虑了在同一源-目的路径上聚合所有应用与采用更灵活的微流方法（受软件定义网络（SDN）概念的启发）之间的对立。我们的仿真结果表明，在有效利用资源和信令开销之间存在着根本性的权衡，而通过使用合适的混合解决方案，我们成功地降低了信令开销。

期刊介绍： As envisioned by Mark Weiser as early as 1991, pervasive computing systems and services have truly become integral parts of our daily lives. Tremendous developments in a multitude of technologies ranging from personalized and embedded smart devices (e.g., smartphones, sensors, wearables, IoTs, etc.) to ubiquitous connectivity, via a variety of wireless mobile communications and cognitive networking infrastructures, to advanced computing techniques (including edge, fog and cloud) and user-friendly middleware services and platforms have significantly contributed to the unprecedented advances in pervasive and mobile computing. Cutting-edge applications and paradigms have evolved, such as cyber-physical systems and smart environments (e.g., smart city, smart energy, smart transportation, smart healthcare, etc.) that also involve human in the loop through social interactions and participatory and/or mobile crowd sensing, for example. The goal of pervasive computing systems is to improve human experience and quality of life, without explicit awareness of the underlying communications and computing technologies. The Pervasive and Mobile Computing Journal (PMC) is a high-impact, peer-reviewed technical journal that publishes high-quality scientific articles spanning theory and practice, and covering all aspects of pervasive and mobile computing and systems.
