Poorvi L. Vora - Research: Voting
My research group has made both constructive and analytical contributions to the study of secure voting systems, and we have prototyped most of the systems we have proposed. Much of our constructive work is based on collaborations with all or part of the Scantegrity team.

Our work has been used by the City of Takoma Park in its municipal elections in 2009 and 2011. I have recently worked on influencing secure voting system policy, see my work on Maryland's election procedures, 2016; my testimony for the Wisconsin recounts, Michigan recounts.

Our focus has been on the new class of voting system known as end-to-end independently verifiable (E2E) voting systems, where voters and observers can audit an election without being required to trust election officials or voting system software. This property is achieved through the use of a digital audit trail made available by the voting system---on a secure bulletin board such as a website---which can be checked by software written by anyone. Thus, while a certain degree of sophistication is necessary in the software used to perform the checks, access to the information and authorship of the software is not restricted. Our work is distinguished from much other work on E2E-V systems in that our protocols possess the dispute resolution property, where, if a voter observes a problem, she can prove it.

We developed the first non-commercial prototype of an E2E system (Citizen-Verified Voting, WOTE II 2004, of Chaum's ``visual cryptography'' scheme), organized the first workshop on the evaluation of voting systems, VSRW 2006, participated in the development and deployment of (a) the first E2E-V system with ballot privacy ever used in a governmental election, Scantegrity, (b) the first accessible prototype of an E2E-V system, Audiotegrity and (c) the first prototype of an E2E-V remote voting system, Remotegrity.

Our most recent work proposes a remote voting system, Apollo, that addresses the credential stealing attack; note, however, that much work remains before internet voting is secure enough for use in governmental elections.

In 2017, I received the Election Verification Network's Public Engagement Award for my work on Maryland's election audits.
