  The large-scale deployment of quantum secret sharing (QSS) in quantum
networks is currently challenging due to the requirements for the generation
and distribution of multipartite entanglement states. Here we present an
efficient source-independent QSS protocol utilizing entangled photon pairs in
quantum networks. Through the post-matching method, which means the measurement
events in the same basis are matched, the key rate is almost independent of the
number of participants. In addition, the unconditional security of our QSS
against internal and external eavesdroppers can be proved by introducing an
equivalent virtual protocol. Our protocol has great performance and technical
advantages in future quantum networks.
