Title:
A novel certificateless deniable authentication protocol

Authors: Chunhua Jin, Chunxiang Xu, Xiaojun Zhang, Qianna Xie, Fagen Li

Abstract:

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 deniable authentication protocols. Then we propose a non-interactive certificateless deniable authentication protocol, by combining deniable authentication protocol with certificateless cryptography. In addition, we prove its security in the random oracle model.
