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.
