Fully Deniable Mutual Authentication Protocol Based on RSA Signature

Xi-Jun Lin and Lin Sun

Abstract

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.
