Semi-quantum secret sharing(SQSS)is a branch of quantum cryptography which only requires the dealer to have quantum capabilities,reducing the difficulty of protocol ***,the efficiency of the SQSS protocol still needs to be further *** this paper,we propose a semi-quantum secret sharing protocol,whose efficiency can approach 100%as the length of message *** protocol is based on single particles to reduce the difficulty of resource *** reordering,a simple but effective operation,is used in the protocol to improve efficiency and ensure ***,our protocol can share specific secrets while most SQSS protocols could *** also prove that the protocol is secure against common attacks.
