Electronic Governance Systems

Abstract

As one of applications in electronic governance, this chapter develops an electronic voting (e-voting) system. After discussing requirements for e-voting systems and reviewing existing approaches, an e-voting system is developed based on confirmation numbers and signature pairs. Here, e-voting systems must satisfy requirements intrinsically contradicting each other, e.g. they must convince anyone that votes from only and all eligible voters had been counted, but at the same time to protect voters from a coercer that forces voters to choose its supporting candidate, correspondences between voters and their votes must be concealed from anyone including election authorities and voters themselves. The developed e-voting system successfully satisfies these requirements. However, it must be noted that these requirement are satisfied under the assumption that at least one of mutually independent multiple authorities is honest.
