A multiparty simultaneous quantum identity authentication protocol based on Greenberger-Horne-Zeilinger (GHZ) states is proposed.The multi-user can be authenticated by a trusted third party (TTP) simultaneously.Compared with the scheme proposed recently (Wang et al 2006 Chin.Phys.Lett.23(9) 2360),the proposed scheme has the advantages of consuming fewer quantum and classical resources and lessening the difficulty and intensity of necessary operations.
