摘要

量子密钥分发被认为是安全的密钥分发, 它为光网络中的安全性问题提供了解决方案。为向金融、军事和电网等领域提供安全的密钥供给服务, 量子密钥分发在光网络中的集成已经引起了广泛关注。目前已有一些研究集中于量子密钥分发在光网络中的集成, 而量子密钥分发光网络的生存性技术研究还几乎处于一片空白。文章针对量子密钥分发光网络中的生存性问题, 提出一种密钥供给服务保护方案, 并仿真验证了网络性能, 结果表明, 所提方法在网络阻塞率、资源利用率和密钥消耗率方面具有较好性能, 为量子密钥分发光网络生存性技术研究提供了重要参考方案。

Abstract

Quantum Key Distribution (QKD) is considered as a secure solution to provide secret keys for the security of optical networks. In order to meet the security demands of fields like finance and military, the integration of QKD into optical networks has attracted much attention. At present, some studies have focused on the integration of QKD in optical networks, while researches on the survivability of optical networks based on QKD is still in a blank. Aiming at the survivability of optical networks based on QKD, this paper proposes protection schemes for key provisioning service, and evaluates the network performances through simulation. The results verify that the proposed method has better network blocking probability, resource utilization and key consumption rate. The proposed scheme provides an important advice for the development of the survivability of optical networks based on QKD.
