Alocação de Recursos em Redes de Distribuição Quântica de Chaves Multiprotocolo

Abstract: As quantum cryptography advances, it becomes crucial to develop methods that optimize resource usage in Quantum Key Distribution (QKD) networks. Facing the challenge of efficiently scheduling and allocating requests this study proposes an approach for multiprotocol QKD networks using quantum resource-aware routing and scheduling strategies. Our model focuses on improving efficiency in the use of quantum keys, routes, and requests, while supporting various quantum communication protocols. Using two real-world QKD topology networks, we tested our proposal in two application scenarios, with different distributions of authentication and cryptography application requests, evaluating the impact of qubit capacity, and request load. The results demonstrate the feasibility of our approach in diverse operational environments.
