摘　　要：Multiparty quantum communication is an important branch of quantum networks.It enables private information transmission with information-theoretic security among legitimate parties.We propose a sender-controlled measurement-device-independent multiparty quantum communication protocol.The sender Alice divides a private message into several parts and delivers them to different receivers for secret sharing with imperfect measurement devices and untrusted ancillary nodes.Furthermore,Alice acts as an active controller and checks the security of quantum channels and the reliability of each receiver before she encodes her private message for secret sharing,which makes the protocol convenient for multiparity quantum communication.
