Abstract

Audit logs are an important tool for post-election investigations, in the event of an election dispute or problem. We propose a new approach to logging that is designed to provide a record of all interactions between each voter and the voting machine. Our audit logs provide a comprehensive, trustworthy, replayable record of essentially everything the voter saw and did in the voting booth, providing investigators a tool for reconstructing voter intent and diagnosing election problems. We show how our design preserves voter anonymity and protects against vote-buying and coercion. We implement a prototype logging subsystem, built on the Pvote voting platform, and demonstrate that the approach is feasible.
