Fully Verifiable and Secure Online Voting
Privacy & SecurityGuaranteeing voter privacy and election security is a multi-step process that needs to be maintained throughout the voting cycle: during voting, vote transmission and the decryption process. This ensures that privacy is maintained from the moment voters mark their ballot through to when ballots are counted.
Integrity & AuditabilityProviding voting process transparency and auditability in an online voting environment is a challenge. Reliable online voting technology ensures voters can verify their votes have been cast and counted correctly, that they have not been tampered, and allows observers and independent auditors to verify the integrity of the online process.
How End-to-End Security and Verifiability Works
Online voting has been designed with flexibility in mind, allowing voter authentication via pre-existing or new voting authentication methods.
Voters make and confirm their selections, votes are encrypted before leaving the voters´ device, ensuring that they remain secret all the way throughout transmission and ballot counting.
Votes are received in the ballot box and without decrypting the votes, voting servers check if the contents of the encrypted votes are valid, allowing to double check for invalid votes.
The integrity of the ballot box is verified by using the bulletin board, digital signatures and mathematical proofs of the votes providing evidence of the accuracy of the counting process and the accuracy of the results.
After the election is closed, online votes are securely transferred for “mixing” by the electoral organization. The mixing process digitally shuffles the votes and breaks the correlation between encrypted votes and voters.
Votes are decrypted using a verifiable mix-net and secret sharing scheme. A quorum of electoral body members is required to regenerate the election key to decrypt the votes.
Once the electoral board decrypts the votes, these are tallied and only visible by the authorized staff, ensuring no results are preliminarily published.
