Abstract: This paper describes Scantegrity, an electronic voting system developed by Chaum et al. (2008b), and it analyses Scantegrity|s ability to satisfy the goals of privacy and verifiability. The paper describes a programmatic attack on Scantegrity and presents findings in the form of program output for a corrupted hypothetical election. The attack takes advantage of the inherent vulnerability of electronic voting systems due to the tension between the goals of privacy and verifiability. It exposes a security weakness in electronic voting systems, and it establishes the need to control code compilation and provide physical security for that compiled code throughout the election process.
