With the rapid development of quantum key distribution (QKD) technology, more various types of QKD protocols are being proposed. Considering the variety of QKD protocols, the exclusivity of quantum channels, the limitation of key generation capability, and the necessity of credibility control, it is a crucial task to explore the cost-effective construction of hybrid QKD networks. In this paper, a hybrid QKD network composed of multiple types of QKD protocols based on trusted-relays is considered from the perspective of topology, and then an analytical model for optimizing the deployment of QKD devices and trusted-relays is proposed to provide secure communication services for a large scale and a wide range of users at the minimum cost. The effectiveness and universality of this proposed analytical model are verified by plentiful simulation results.
