An axiomatic re-characterization of the Kemeny rule
The Kemeny rule is one of the well studied decision rules. In this paper we show that the Kemeny rule is the only rule which is unbiased, monotone, strongly tie-breaking, strongly gradual, and weighed tournamental. We show that these conditions are logically independent
Condorcet versus participation criterion in social welfare rules
Moulin (1988) shows that there exists no social choice rule, that satisfies the following two criteria at the same time: the Condorcet criterion and the participation criterion, a.k.a., No Show Paradox. We extend these criteria to social welfare rules, i.e., rules that choose rankings for each preference profile. We show that the impossibility does not hold, and one particular rule, the Kemeny rule satisfies both the Condorcet and the participation criteria
Double Voter Perceptible Blind Signature Based Electronic Voting Protocol
Mu et al. have proposed an electronic voting protocol and
claimed that it protects anonymity of voters, detects double
voting and authenticates eligible voters. It has been shown that
it does not protect voter\u27s privacy and prevent double voting.
After that, several schemes have been presented to fulfill these
properties. However, many of them suffer from the same
weaknesses. In this paper, getting Asadpour et al. scheme
as one of the latest one and showing its weaknesses, we propose
a new voting scheme which is immune to the weaknesses
of previous schemes without loosing efficiency. The scheme,
is based on a special structure, which directly
use the identity of voter, hides it in that structure and reveals
it after double voting. We also, show that the security of this
scheme depends on hardness of RSA cryptosystem, Discrete Logarithm
problem and Representation problem
