TAILIEUCHUNG - You Go to Elections with the Voting System You Have: Stop-Gap Mitigations for Deployed Voting Systems

The showcase argument points out that mega-events are spectacles that can best be understood as either instruments of hegemonic power (Ley and Olds, 1988) or public- relations’ ventures far removed from the realities of urban problems and challenges. Whatever the motivation, there is increased awareness that the mega-event can also be a vehicle for some form of urban transformation. While there are usually significant conflicts between event requirements and post-event usage (Servant and Takeda, 1996: 104), the substantial fiscal demands of these projects has typically included some form of permanent alteration to the urban environment. Particularly in postindustrial cities, the mega-event is often linked to inner-city renewal and. | You Go to Elections with the Voting System You Have Stop-Gap Mitigations for Deployed Voting Systems J. Alex Halderman Princeton University Hovav Shacham University of California San Diego Abstract In light of the systemic vulnerabilities uncovered by recent reviews of deployed e-voting systems the surest way to secure the voting process would be to scrap the existing systems and design new ones. Unfortunately engineering new systems will take years and many jurisdictions are unlikely to be able to afford new equipment in the near future. In this paper we ask how jurisdictions can make the best use of the equipment they already own until they can replace it. Starting from current practice we propose defenses that involve new but realistic procedures modest changes to existing software and no changes to existing hardware. Our techniques achieve greatly improved protection against outsider attacks they provide containment of viral spread improve the integrity of vote tabulation and offer some detection of individual compromised devices. They do not provide security against insiders with access to election management systems which appears to require significantly greater changes to the existing systems. 1 Introduction The widespread deployment of electronic voting equipment has put voting officials in a difficult position. On the one hand the equipment has been deployed at great expense and transitioning away from it is difficult. On the other hand every serious review of these systems has discovered significant flaws. For instance in every electronic voting system that has been studied researchers have been able to compromise polling place devices with access similar to what a voter or pollworker would have. In several of the systems it appears to be possible to design a virus that delivered to a single polling place device could propagate through the Election Management System EMS to every device in the county. Moreover detecting attacks may be difficult as no good
