A non-interactive quantum deniable authentication protocol based on asymmetric quantum cryptography

In order to reduce the communication cost, a non-interactive quantum deniable authentication based on asymmetric quantum cryptography is proposed. In the new scheme, the sender and receiver without interaction first agree a sharing secret key by utilizing their public and private key and then the sender generates the authentication information according to the sharing secret key, similarly, the receiver can also generate the same authentication codes according to the sharing secret key. So the receiver cannot prove the source of the message to a third party but can identify the true source of a given message. Compared with our previous schemes based on interaction, this new scheme has the remarkable advantages of reducing the communication cost, lessening the difficulty and intensity of necessary operations, and without help of a trusted center. Finally, the security analysis results show that this new scheme also satisfies the same basic security requirements of deniable authentication protocol such as completeness, deniability, and can withstand forgery attack, impersonation attack and inter-resend attack.
