Comment : | (Illustration not included here) Figure 1: Voting process on a DRE-VVPAT system enhanced with an Audit Module In the first step the voter makes the selection of the desired voting options for all the races in the DRE, as usual. The selected options are transferred, in a second step, from the DRE to the printer through the Audit Module. A paper record containing the selected options is then printed (and/or read through headphones). In the third step, the voter verifies (via the paper record and/or audio) the selected options and eventually accepts them by pressing a button on the Audit Module. At this point, the Audit Module knows the exact voting options that have been verified by the voter via the VVPAT. The Audit Module informs the DRE that the verification by the voter has been positive. In response, the DRE digitally signs the voting options and sends this digital signature to the Audit Module (fourth step). The Audit Module can then check the validity of this digital signature to ensure not only that it is valid but also that it is generated based on the correct voter-verified voting options. Any problem that could invalidate the signature of the vote would be detected at this point by the Audit Module. If the signature is correct, the Audit Module also digitally signs the (digitally signed) voting options received from the DRE. In the fifth step, the resulting digital signature is sent from the Audit Module to the printer (this digital signature can be printed on the paper record as a bar code) and to the DRE. The DRE might verify the validity of this second signature and might store it with the electronic vote. Finally, the Audit Module also stores the digitally signed vote to enhance the redundancy of the voting system.
