Routing Performance Based On Software Defined Quantum Key Distribution Network

Quantum Key Distribution (QKD) takes a short time to process encryption and authentication messages as an advanced security key distribution. Open Shortest Path First (OSPF) routing used on existing QKD networks uses more security keys. Software-Defined Networking (SDN) exists to control the core network, make routes easier to find and reduce the use of security keys. One of the benefits of SDN is that the controller can customize the routing scheme and save the use of secure keys. Based on the topology and scenarios, the link state protocol test results show that using keys increased the number of hops traversed by five to fourteen keys. We can see the five keys constant when testing the distance vector protocol. The average test time difference between the two protocols is about 3.438 seconds for the link state protocol and 2.687 seconds for the distance vector algorithm.
