The notion of deniable authentication protocol was introduced in 1998 by Dwork et al. [11] and Aumann and Rabin [1, 2] independently. As a new cryptographic authentication protocol, a deniable authentication protocol enables an intended receiver to identify the source of a given message without being able to prove the identity of the sender to a third party. Over the past years, many deniable a...

A deniable authentication protocol allows a sender to transfer an authenticated message to a receiver in such a way that the receiver cannot prove to a third party about the source of the message. In recent years, many deniable authentication protocols have been proposed. In 2005, Lu et al. proposed a secure and non-interactive deniable authentication protocol based on factoring. Although Lu et...

Deniable authentication protocol is different from traditional authentication protocol in that the intended receiver can authenticate the source of a given message, but cannot prove the source to a third party. In recent years, many deniable authentication protocols have been put forth. To adapt to some special group communication requirements, in this paper, we will propose a new group oriente...

Deniable authentication protocols allow a sender to authenticate a receiver, in a way that the receiver cannot convince a third party that such authentication (or any authentication) ever took place. In this study, we construct a fully deniable mutual authentication protocol based on RSA signature, and then a deniable authenticated key exchange protocol is constructed from the proposed protocol.

Deniable authentication protocol is a new authentication mechanism in secure computer communication, which not only enables an intended receiver to identify the source of a received message but also prevents a third party from identifying the source of the message. In this paper, based on the Diffie-Hellman algorithm, we propose a new simple deniable authentication protocol from a provably secu...

A deniable authentication protocol enables a receiver to identify the true source of a given message, but not to prove the identity of the sender to a third party. This property is very useful for providing secure negotiation over the Internet. Consequently, many interactive and non-interactive deniable authentication protocols have been proposed. However, the interactive manner makes deniable ...

Deniable authenticated protocol is a new and attractive protocol compared to the traditional authentication protocol. It allows the appointed receiver to identify the source of a given message, but not to prove the identity of the sender to a third party even if the appointed receiver is willing to reveal its private key. In this paper, we first define a security model for certificateless denia...

In 1998, Dwork et al. first proposed an application of zeroknowledge, deniable authentication protocol. Thereafter, there were many researches about the deniable authentication schemes. In 2004, Shao demonstrated out that the previous schemes had a common weakness in which any third party can impersonate the intended receiver to verify the signature of the given message, and they proposed a new...

Tel: 886+(0)5-2721001 ext.2017 Abstract Recently, Yoon et al. and Cao et al. propose two deniable authentication protocols respectively. They both claim that their protocols can achieve the deniable property. However, in this paper, we will point out that their protocols each suffers from some malicious attacks. After that, we propose a new identity-based deniable authentication protocol on pai...
