ABSTRACT
Electronic voting has been attracting considerable attention during the last years. The interest in e-
voting is based on one hand upon interest and attention devoted to e-government, e-democracy, e-
governance, etc. On the other hand, interest in e-voting is founded in problems with domestic election
systems, e.g. violence, intimidation, ballot stuffing, under-age and multiple voting, counting error, complicity
of the security agencies and the absence or late arrival of election materials lacking e.t.c. However, without
appropriate security measures, electronic based elections can be a challenge. This paper reviews four generic
cryptographic models that were proposed in the academic literature for secure electronic voting and provides
a comparison amongst the four models in terms of their core properties of universal verifiability, support for
write-in ballot, efficient voting, efficient tallying and large scale election support.
KEYWORDS: e-voting, election, homomorphic model, mix-net model, blind signature model, verifiable

1. INTRODUCTION
Elections allow the populace to choose their representatives and express their preferences for how
they will be governed. Naturally, the integrity of the election process is fundamental to the integrity of
democracy itself. The election system must be sufficiently robust to withstand a variety of fraudulent
behaviors and must be sufficiently transparent and comprehensible that voters and candidates can accept the
