Electronic Jury Voting Protocols
Alejandro Hevia and Marcos Kiwi
Abstract: This work elicits the fact that all current
proposals for electronic voting schemes disclose the final
tally of the votes.
In certain situations, like jury voting, this may be undesirable.
We present a robust and universally verifiable
Membership Testing Scheme (MTS) that allows, among other things,
a collection of voters to cast votes and determine whether
their tally belongs to some pre--specified set (e.g., exceeds a
--- our scheme discloses no additional information than that implied
from the knowledge of such membership.
We discuss several extensions of our basic MTS.
All the constructions presented
combine features of two parallel lines of research
concerning electronic voting schemes, those based on MIX--networks
and in homomorphic encryption.
