Cryptanalysis of a Deniable Authentication Protocol based on Bilinear Pairing using Single Sender and Group Sender

چکیده
The aim of an efficient deniable authentication protocol is to enable a receiver to identify the source of a given message but not to prove the identity of the sender. Lu and Cao [7,10] confirmed that the previous protocols 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 protocol based on bilinear pairing using single sender and sender group. They claimed that their protocol could provide complete security and properties of a deniable authentication protocol based on bilinear pairing using single sender and sender group, we will point out that the protocol in two papers is unable to prove the source of the given message to any third party, even if he/she fully cooperates with the third party.

Group Oriented Identity-based Deniable Authentication Protocol from the Bilinear Pairings
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...
متن کاملCryptanalysis of a Non-interactive Deniable Authentication Protocol Based on Factoring
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...

متن کاملFully Deniable Mutual Authentication Protocol Based on RSA Signature
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.
