While ensuring security, research on the QSS protocol also focuses on whether it can be both efficient and implementable. One of the main methods to improve the efficiency of QSS protocol is to reduce quantum resource consumption, so that the required qubits for transmitting 1 bit information are minimized as much as possible. This paper proposes an efficient multiparty QSS scheme based on the new kind of measuring-basis-encrypted, which encrypts the basis information of the qubits received by each agent by the sub-secrets of other agents, and significantly improve the protocol efficiency by splitting the keys to distributing. Without any quantum storage, the new QSS scheme can reach half of the theoretical efficiency of the ring-kind QSS protocol by sharing 1 bit secret information by 2 qubits, while ensuring both security and experimentability.
