Abstract：Inorder topreventkeyleakagecausedbyentityatacksinquantumkeydistribution，amethodof multi-entity jointidentityauthenticationbasedonextendedquantumkeydistribution（QKD）isproposed.TheQKDprocessisanalyzedto determine theofQKDmodel.Inorder toensuretherandomnessof quantumkeys，interpolationisusedtoexpandthequantum keylibrarytoincreaseitssize.Themulti-entitydistributionofextendedquantumkeyiscariedout.Duringthemulti-entity process of QKD，thefour formsof quantum Bellstatesareused foruseridentityauthenticationandkeygeneration.The experimentalresultsshow thattheproposedmethodcanuse QKDprotocoltoachieveaquantumutilizationrateof95%.In comparison withbefore expansion，therandomnessof theexpandedquantumkeylibrary hasbeen improved significantly.The atackexperimentsofQKDprocesshowthatthismethodcanfullyrecognizetheentityidentityandrefusetodistributequantum keys to attackers.
