摘　　要：本文提出了一种基于d维Bell态的单态多方半量子秘密共享(Multiparty Semiquantum Secret Sharing,MSQSS)协议,该协议可以实现“只有当所有接收方协同工作时才能恢复发送方的密钥”这一目标.该协议被证实能够抵抗外部攻击和参与者攻击.该协议适用于d维量子系统,仅采用一种d维Bell态作为初始量子资源,且既不需要量子纠缠交换,也不需要酉操作.A single-state multiparty semiquantum secret sharing(MSQSS)scheme with d-dimensional Bell states is proposed,which can accomplish the goal that only when all receivers work together can they restore the sender's secret key.This protocol is validated to be secure against both the outside attack and the participant attack.This protocol is adaptive for the d-dimensional system,which only employs one kind of d-dimensional Bell states as initial quantum resource and needs neither quantum entanglement swapping nor unitary operations.
