Abstract:	In deniable authentication protocols, the senders' right cannot be protected due to the deniable property. The deniable property causes the receiver's implication because the sender cannot prove the sender's identity to the third party. To overcome this problem, Hwang and Ma first proposed their protocol with sender protection to provide evidences for the sender. To protect senders' privacy, it is better that the senders should be anonymous. Therefore, a deniable authentication protocol with anonymous sender protection is proposed. The extra bonus of our sender protection is that, in our protocol, the sent deniable messages can be converted to undeniable signatures without additional computational cost. Then the converted signatures can be directed used in real applications.
