According to the entanglement features of GHZ (Greenberger-Horne-Zeilinger) states, a quantum secret sharing protocol based on the five-particle GHZ state is designed. In the protocol, the quantum sequence of the five-particle GHZ state is prepared by the initiator, and the total number of the secret sharing parties is 4. Only when all the four people are involved in decryption can the secret information be solved. The correctness and security of the protocol are analyzed, and the results show that the protocol can be used to resist the interception retransmission attack, the man-in-the-middle attack and the entanglement attack. When the temptation particles exist, the probabilities of being found for the eavesdroppers under different noise environments are obtained by using the modeling tool Prism.
