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.
