摘要

为了保障电力调度业务数据传输的安全性，提出了一种面向电力调度业务的量子密钥供给及动态调整算法。首先，根据调度业务的重要程度，确定了密钥应用方式，并给出了密钥池容量计算方案。其次，基于密钥更新频率和密钥应用方式设计了量子密钥动态调整算法。最后，建立了调度系统业务模型，针对点对点和点对多点两种架构对算法在不同场景中的应用性能进行了仿真测试。测试结果表明，该算法可以很好地实现量子密钥在设定时间内的动态调整，进而提升调度数据网数据传输的安全性。

Abstract

In order to ensure the transmission security of electric power dispatching service data

a quantum key supply and dynamic adjustment algorithm was provided.Firstly

the key application mode was determined according to the priority of different services

and the calculation method of the key pool capacity was also provided.Secondly

the quantum key dynamic adjustment algorithm was designed based on the key update frequency and application mode.Finally

the traffic model for the dispatching system was established

and the algorithm’s application performance for different scenarios was simulated within point-to-point/multipoint architectures.The test results show that the algorithm can realize the dynamic key adjustment in the selected adjustment period

and thus improves the security of the scheduling data transmissions.
