The proposed quantum identity authentication schemes only involved authentication between two communicators, but communications with deniability capability are often desired in electronic applications such as online negotiation and electronic voting. In this paper, we proposed a quantum deniable authentication protocol. According to the property of unitary transformation and quantum one-way function, this protocol can provide that only the specified receiver can identify the true source of a given message and the specified receiver cannot prove the source of the message to a third party by a transcript simulation algorithm. Moreover, the quantum key distribution and quantum encryption algorithm guarantee the unconditional security of this scheme. Security analysis results show that this protocol satisfies the basic security requirements of deniable authentication protocol such as completeness and deniability and can withstand the forgery attack, impersonation attack, inter-resend attack.
