Abstract

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.
