A ID-Based Deniable Authentication Protocol on pairings
Jue-Sam Chou and Yalin Chen and Jin-Cheng Huang
Abstract: Recently, Yoon et al. and Cao et al. propose two deniable authentication protocols
respectively. They both claim that their protocols can achieve the deniable property.
However, in this paper, we will point out that their protocols each suffers from some
malicious attacks. After that, we propose a new identity-based deniable authentication
protocol on pairings which can not only attain the desired deniable property but also
can prevent attacks.
