Abstract We show that a potential eavesdropper can eavesdrop whole secret information when the legitimate users use secure carrier to encode and decode classical information repeatedly in the protocol proposed by Bagherinezhad S and Karimipour V [Phys. Rev. A 67(2003)044302]. Then we present a revised quantum secret sharing protocol by using the Greenberger--Horne--Zeilinger state as secure carrier. Our protocol can resist Eve’s attack.
