“…Such a process is often known as a client-server operation. The client-server topology reconcile and verify the keys reservation and their subsequent distribution for their business need and data encryption [52]. In addition, the key management layer in the QKD-DWDM network should be designed in such a way as to be able to support multi-point to multi-point communication.…”

Quantum key distribution (QKD) can ensure information security between two remote parties. To commercialise QKD technology successfully, it should be integrated with dense wavelength division multiplexing optical transport. However, various challenges limit the QKD's performance in terms of the quantum key rate, quantum bit error rates, and maximum achievable distance. In this study, the authors discuss some of the major practical limiting factors for QKD performance such as spontaneous Raman scattering, four-wave mixing, and amplified spontaneous emission.

“…Some work has been done to study the architecture required for securing communications within a network scenario. In [6] and [7], a conceptual framework is presented consisting of QKD, key management, and application layers. The key management layer implements the standard Key Management Interoperability Protocol (KMIP) [8].…”

Quantum Key Distribution (QKD) is a means of generating keys between a pair of computing hosts that is theoretically secure against cryptanalysis, even by a quantum computer. Although there is much active research into improving the QKD technology itself, there is still significant work to be done to apply engineering methodology and determine how it can be practically built to scale within an enterprise IT environment. Significant challenges exist in building a practical key management service for use in a metropolitan network. QKD is generally a point-to-point technique only and is subject to steep performance constraints. The integration of QKD into enterpriselevel computing has been researched, to enable quantum-safe communication. A novel method for constructing a key management service is presented that allows arbitrary computing hosts on one site to establish multiple secure communication sessions with the hosts of another site. A key exchange protocol is proposed where symmetric private keys are granted to hosts while satisfying the scalability needs of an enterprise population of users. The key management service operates within a layered architectural style that is able to interoperate with various underlying QKD implementations. Variable levels of security for the host population are enforced through a policy engine. A network layer provides key generation across a network of nodes connected by quantum links. Scheduling and routing functionality allows quantum key material to be relayed across trusted nodes. Optimizations are performed to match the real-time host demand for key material with the capacity afforded by the infrastructure. The result is a flexible and scalable architecture that is suitable for enterprise use and independent of any specific QKD technology.

“…Other techniques involve multi-party key distribution at the level of the quantum protocol 10,11 but with less applicability to existing QKD devices. KMS designs for large scale networks 12 or with focus on secure key forwarding 13 have been studied before, as well as QKD analysis in light of network topology and performance indicators 14 , but without a practical and scalable approach for key forwarding in the various scenarios we have proposed. Similar linear programming approaches have been used for entanglement distribution 15,16 and for physical-level wavelength-division multiplexing 17,18 .…”

Nowadays QKD plays a critical role in unconditionally-secure and quantum-safe key distribution. Commercially available QKDdevices are getting more popular for institutional and governmental national and international networks, but are expensive andoffer limited key rates. We provide a formalization of QKD-generated key forwarding and redistribution at the KMS level byextending the network graph of physical QKD links to the complete graph with logical links, and we investigate its application onthree practical scalable scenarios (all-to-all, one-to-all, one-to-one). We define a maximization goal for each scenario, andprovide a linear programming problem statement to compute the optimal redistribution. We perform an extensive analysis ofthe algorithm in terms of forwarding results and key consumption on simulated QKD networks and discuss the implications ofnetwork size and graph topology on the algorithm’s performance and complexity.
