In the world’s largest-ever deployment of online voting, the iVote Internet voting system was trusted for the return of 280,000 ballots in the 2015 state election in New South Wales, Australia. During the election, we performed an independent security analysis of parts of the live iVote system and uncovered severe vulnerabilities that could be leveraged to manipulate votes, violate ballot priva...

In this work we present an energy efficient leader election protocol for anonymous radio network populated with n mobile stations. Previously, Nakano and Olariu have presented a leader election protocol that terminates, with probability exceeding 1 − f ( f ≥ 1), in log log n + o(log log n) + O(log f ) time slots [14]. As the above protocol works under the assumption that every station has the a...

Control of elections refers to attempts by an agent to, via such actions as addition/deletion/partition of candidates or voters, ensure that a given candidate wins [BTT92]. An election system in which such an agent’s computational task is NP-hard is said to be resistant to the given type of control. The only election systems known to be resistant to all the standard control types are highly art...

The second significant digits of precinct-level (or polling station-level) vote counts follow regular patterns when voters are acting strategically and when there are partisan imbalances of voters in districts (when there is a gerrymander). The digits often follow distinctive patterns when vote counts are affected by coercion. The patterns are illustrated by a simulation exercise that generates...

Although, there exists numerous literature on the procedure for forecasting or predicting election results, in Ghana only opinion poll strategies have been used. To fill this gap, the paper develops Markov chain models for forecasting the 2016 presidential election results at the Regional, Zonal (i.e. Savannah, Coastal and Forest) and the National levels using past presidential election results...

Introduction By the time of the 2005 general election, most UK parties had been running websites and using online campaign tools for a decade or more. This was the third general election campaign in which the internet, World Wide Web (WWW) and email had played a role, but the first one where the majority of the UK electorate now had access. 1 Whilst the initial hype surrounding the democratisin...

The fair way to decide an election between two candidates a and b is majority rule; if more than half the electorate prefer a to b, then a is elected; otherwise b is elected. Arrow’s theorem asserts that no fair election procedure exists for choosing from among three or more candidates. This note gives an exposition of Arrow’s theorem. It also describes the relation of election procedures betwe...

The winners of an election are usually satisfied with the outcome, but it is often more challenging to persuade the losers (and their supporters) that they lost. To that end, it is not sufficient that election results be accurate. The public must also know the results are accurate, which can only be achieved if conduct of the election is sufficiently transparent that candidates, the press, and ...

In clustered sensor networks, electing CHs (Cluster Heads) in a secure manner is very important because they collect data from sensors and send the aggregated data to the sink. If a compromised node is elected as a CH, it can illegally acquire data from all the members and even send forged data to the sink. Nevertheless, most of the existing CH election schemes have not treated the problem of t...
