Abstract: To simplify the implementation of quantum secret sharing, a protocol based on Bell states entanglement swapping was proposed. The quantum channels among all players constituted a ring. Through adding or deleting nodes in the ring, protocols for any number of players could be designed. Investigation shows that the protocol is secure against the eavesdropping not only by eavesdroppers but also by the players.

Key words: quantum secret sharing, entanglement swapping, quantum cryptography
