Cryptographic Methods for Storing Ballots on a Voting Machine

Abstract:
A direct recording electronic (DRE) voting machine must satisfy
several requirements to ensure voter privacy and the integrity of the
election. A recent proposal for a vote storage system due to Molnar et
al. provides tamper-evidence properties while maintaining voter
privacy by storing ballots on a programmable, read-only memory (PROM).
We achieve the same properties and protect against additional threats
of memory replacement through cryptographic techniques, without the
use of special hardware. Our approach is based on a new cryptographic
primitive called History-Hiding Append-Only Signatures.
