Abstract

We present the design and implementation of Sensus, a practical,secure and private system for polling (conducting surveysand elections) over computer networks. Expanding onthe work of Fujioka, Okamoto, and Ohta, Sensus uses blindsignatures to ensure that only registered voters can vote andthat each registered voter only votes once, while at the sametime maintaining voters' privacy. Sensus allows voters toverify independently that their votes were counted correctly,and anonymously challenge the results should their votes bemiscounted. We outline seven desirable properties of votingsystems and show that Sensus satisfies these properties well,in some cases better than traditional voting systems.
