TL;DR: A framework of key as a service (KaaS) is proposed to jointly overcome the two challenges of efficiently deploying and employing secret keys over QKD-integrated optical networks and the success probabilities of KP assembly and VKP assembly are defined to evaluate the benefits of KaaS.

TL;DR: The extensive simulations indicate that the proposed approaches are effective in reducing the cost of deploying QKD-over-WDM backbone networks, where the designed CEQN algorithm is efficient to demonstrate similar to the ILP model.

TL;DR: Evaluating the impact of protection on network security verifies a trade-off that exists between how much protection can be provided for key services versus the overall security of the network, given a certain resource budget.

TL;DR: This study introduces the software defined networking (SDN) technique to overcome the challenge of providing efficient and flexible QaaS for fulfilling the SKR requirements of multiple users over a QKD network infrastructure and presents the protocol extension, intercommunication workflow, and routing and SKR assignment strategy for QAAS implementation in the SDQaaS framework.

TL;DR: A trade-off can be achieved between the recovery of key provisioning services and the delivery of the QKD on wavelength resources and secret-key resources to achieve resiliency of the network.
