Hyun-Kyo Lim, Chankyun Lee, Wonhyuk Lee · 2024
In order to effectively utilize the costly quantum resource in the practical quantum-secured networking, we proposed lifetime-aware quantum key relay algorithm. The proposed algorithm calculates an end-to-end quantum key relay path, based on the combination of the lifetime and the number of quantum keys of links. In the practical condition, the proposed algorithm reduces 21% of blocking count of quantum-secured service, from that of the conventional key relay algorithm.
