摘要
量子密钥分发光网络指量子设备通过光纤进行互联,为不同节点对之间提供分发密钥功能的网络。在量子密钥分发光网络中,密钥池结合密钥资源具有“逐渐累积,瞬间消耗”的特点,可实现对密钥资源的高效存储与管理。本文分析量子密钥分发技术的特点及密钥池的功能意义,设计密钥即服务框架及基于密钥池的量子密钥分发光网络架构,提出基于该架构的密钥池构建方法和密钥资源调度方法,并进行仿真验证。
Abstract
A quantum key distribution based optical network is a network formed by the interconnection of quantum key distribution devices through optical fibers. In the quantum key distribution optical networks, the key pool combines the characteristics of gradual accumulation and instantaneous consumption of secret keys to realize the efficient storage and management of key resources. This study analyzes the characteristics of quantum key distribution technology and the functional significance of the key pool. In addition, this study proposes a design of the “key as a service” framework and the quantum key distribution optical network architecture based on the key pool. A key pool construction method and a key resource scheduling method based on the architecture are proposed, and they are verified by a network simulation.
