A ID-Based Deniable Authentication Protocol on pairings
Jue-Sam Chou Yalin Chen Jin-Cheng Huang
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.

A Novel Secure Electronic Voting Protocol Based On Bilinear Pairings
Jue-Sam Chou Yalin Chen Jin-Cheng Huang
In 1997, Cranor and Cytron proposed an electronic voting protocol, Sensus protocol, intended to be applied in a real election. However, in 2005 Fabrizio et.al. pointed out there is a vulnerability exists in their protocol that the validator can impersonate anyone of those abstained voters to cast vote. They proposed a scheme, Seas protocol, to solve this weakness. But in this paper, we will show that Seas protocol is not only inefficient but also impractical. Moreover, we also propose a sound electronic voting protocol based on Sensus protocol from bilinear pairings, which can really satisfy the security requirements of an e-voting system.
