A new n-party quantum secret sharing model based on multiparty entangled states

Recently, multiparty entanglement is becoming an important physical resource to design some typical quantum cryptography protocols. In this paper, we firstly proposed two special QSS protocols with the multiparty entangled states $|{\chi }_n⟩$ and $|S_n⟩$. Then, their security has been proved to resist existing attacks. Furthermore, a new QSS model has been summarized by analyzing the property of the used multiparty entangled states. Moreover, compared with some other QSS protocols based on multiparty entangled states, it can be seen that our protocol is efficient in quantum communication and computation.
