This paper shows how to use signature schemes for deniableauthentication. Deniable authentication means that a messagereceiver R, although received a message m from a sender S,cannot convince a third party that the sender S has sent R themessage m. Obviously, signature schemes secure againstexistential forgery are unsuitable for such a deniabilityproperty. However, if signature schemes are just secure againstselective forgery, we can construct a deniable authenticationprotocol. The protocol is presented in the extension framework ofRaimondo et al. as a deniable message transmission (MT)authenticator.
Keywords:Authentication; Digital Signatures; Privacy-Enhancing Technologies
