    "abstract": "Extending the eavesdropping strategy devised by Zhang, Li and Guo [Phys. Rev.\nA 63, 036301 (2001)], we show that the multiparty quantum communication\nprotocol based on entanglement swapping, which was proposed by Cabello\n[quant-ph/0009025], is not secure. We modify the protocol so that entanglement\nswapping can secure multiparty quantum communication, such as multiparty\nquantum key distribution and quantum secret sharing of classical information,\nand show that the modified protocol is secure against the Zhang-Li-Guo\u0027s\nstrategy for eavesdropping as well as the basic intercept-resend attack.",
