Group Oriented Deniable Authentication Protocol
Rongxing Lu, Zhenfu Cao, Xiaolei Dong, Renwang Su · 2006
Deniable authenticated protocol is a new cryptographic authentication protocol that 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. Therefore, it can be applied to many practical situations. Over the past years, plenty of deniable authentication protocols have been put forth. In this paper, based on the elliptic curve cryptosystem, we would like to propose a novel group oriented deniable authentication protocol. In our proposed protocol, the number of the senders reaches the qualified threshold value, and then these senders can send a deniable authentication message to an intended receiver
