The document describes an e-voting application that uses barcodes and paper audit trails to provide an isolated and secure e-voting system at the precinct level. It discusses the components, scenario, and processes involved in administering an election using this system, including voter verification, vote casting, sealing and collecting votes, and managing results and audit information.

2. e-Voting Application e-Voting Application is an open source project aiming to create an e-voting system which complies to European e-Voting standard and EML specification.

3. e-Voting Application is also used as basis to create an e-voting system which complies to Indonesian e-Voting standard which is being defined by Badan Pengkajian dan Penerapan Teknologi (BPPT).

4. Download and License e-Voting Application can be found here: http://sourceforge.net/projects/evotingapp/ It is under the license GPL v3, basically means: You may download, modify, use and redistribute it freely.

5. Derived works should be made open source too under the same license.

6. e-Voting Application Components Client side applications: Vtoken Generating application (VG). √

7. e-Voting Machine application (EVM). √

8. Vote Counting application (VC). Server side systems: e-Voting Tabulation system (EVT).

9. e-Voting Scenario Voting opening Administrator opens voting process. Voting session Administrator generates vtoken using VG.

10. Voters cast vote using EVM. Voting closing Administrator closes voting process.

11. VG/EVM generates result in files. Result delivery Administrator sends result to election body.

12. Voting Opening VG EVM EVM EVM Administrator opens voting in VG machine and all EVM machines

13. Voting Opening Administrator opens voting process on the machine by pressing an open voting button on VG/EVM.

14. When opening voting process, VG/EVM: Activates and deactivates some functions.

15. Generates a pair of private key – public key for digital signature: VG: vtoken-private.bin and vtoken-public.bin

16. EVM: private.bin and public.bin vtoken-public.bin is then copied from VG machine to each EVM machine.

17. Voting Opening Before administrator open voting process on the machine, VG: cannot be used to generate vtoken.

18. can be used to reset ballot box. After administrator open voting process, VG: can be used to generate vtoken.

19. cannot be used to reset ballot box.

20. Voting Opening Before administrator open voting process on the machine, EVM: cannot be used to cast votes.

21. can be used to view result.

22. can be used to reset ballot box. After administrator open voting process, EVM: can be used to cast votes.

23. cannot be used to view result.

24. cannot be used to reset ballot box.

25. Voting Session 1. Administrator verifies voter and gives vtoken barcode 2. Voter validates vtoken barcode and casts vote 4. Voter puts paper audit trail into audit box 3. Voter takes paper audit trail VG EVM Entry Exit

26. Voting Session Voter verification Administrator verifies voter identity. Vtoken generation Administrator generates vtoken as proof of right-to-vote using VG machine. Vtoken validation EVM validates vtoken before voting. Voting Voter casts vote using EVM.

27. Voting Session Vote sealing EVM seals “vtoken + vote” using digital signature. Vote collection EVM collects sealed votes in ballot box electronic. Paper audit trail generation Voter takes generated paper audit trail and puts into audit box.

28. Voter Verification Before voter casts a vote, administrator verifies for two things: voter's identity, and

29. whether voter is eligible to vote. Administrator performs voter verification: manually using traditional identity card, or

30. electronically using digital identity card, or

31. combination of both.
