E2E Verifiable Borda Count Voting System without Tallying Authorities
Samiran Bag, Muhammad Ajmal Azad, Feng Hao · 2019
An end-to-end verifiable (E2E) voting system enables candidates, voters and observers to monitor the integrity of an election process and verify the results without relying on trusted systems. In this paper, we propose a DRE-based Borda count e-voting system called DRE-Borda. The proposed system is E2E verifiable without involving any tallying authorities. Furthermore, it outputs only the total score a candidate gets without revealing any other information such as the breakdown of scores with respect to different ranks. This reduces the information leakage from the tallying result to the minimum, hence effectively preventing Italian attacks. When the DRE machine is completely compromised, the integrity of the tallying result is still preserved and what an adversary can learn from a compromised machine is strictly limited to the partial tally at the time of compromise.
