Trusted3Ballot: Improving Security and Usability of ThreeBallot Voting System using Trusted Computing

Abstract

The main goal in the design of ThreeBallot system was to provide an end-to-end auditable voting system in a simple way without use of cryptography to bolster voter confidence in the system. However, later it was shown that this system has significant security and usability problems. To solve these problems, in this work we propose Trusted3Ballot; an electronic ThreeBallot based voting system which uses trusted computing technology. One notable feature of the proposed system is the use of TPM remote attestation property to address a number of trust and security problems. The analysis of our proposal reveals that significant improvements to the ThreeBallot system are provided in terms of both security and usability.
