Elections and Electronic Voting
We have had a several different thrusts to our work with elections and electronic voting.
One key thrust is to explore process composition tools as applied to elections, concentrating particularly on mail-in and Internet voting. This includes exploration of how to compose systems from pre-analyzed process components, how to analyze the vulnerability of these systems to attacks, and how to guarantee that important security properties are ensured for the resulting composed system. The underlying processes represent aspects of national and local elections, their composition produces an election process, and analysis of the composition gives insight into potential errors or attacks on the election. Providing an approach for formally reasoning about human participation extends current security work. The project also breaks new ground by exploring process-based approaches for modeling and defending against attacks.
The thrust that we have examined previously looked at auditing. Election auditing verifies that the systems and procedures work as intended, and that the votes have been counted correctly. If a problem arises, forensic techniques enable auditors to determine what happened and how to compensate if possible. Complicating this is that the audit trails enabling analysis of failures may contain information that either exposes the identity of the voter (enabling voter coercion, for example); or that communicates a message to a third party (enabling vote selling). The goal of this project was to determine the information needed to assess whether the election process in general, and e-voting machines in particular, operate with the desired degree of assurance, especially with respect to anonymity and privacy.
We work closely with the Marin County Registrar of Voters' office and the Yolo County Clerk-Recorder's office.
We also collaborate closely with Lee Osterweil, Lori Clarke, George Avrunin, and their graduate students and postdocs in the LASER Lab at UMass Amherst.
