Subject: Indian Election EVM (electronic voting machines)
Team, Some useful notes and links of interest to contrast and compare. DW ----- Original Message ----- > > Hi Ron (and other authors of this paper), > > I was going through the rebuttal document and found this > interesting mention of Indian EVMs at section 4 ("Miscellaneous > Errors") of the document. > > "Finally, in his §1.5, Shamos implicitly argues that DREs are suitable > for America because India has chosen to use them nationwide. The > authors fail to understand Shamos s intent here. Perhaps he will issue > an updated version of his paper explaining his argument more clearly?" > > I have not read Shamos' original paper, but there are a few key > differences between the Indian EVMs that were used in the Indian > general elections last time and the American DREs, like the Diebolds. > > 1. First of all, the Indian EVM is basically a hardware device with very little > software components. All the logic of the device is embedded into > firmware, a microchip specifically designed for the purpose of > recording the votes.

The amount of intelligence in the voting system itself is minimal. > The voting system has no idea of the candidates, their names etc. The > system can be considered essentially as a 16-way electronic slotting > system, which can record upto 3,840 votes in all these 16 slots. The > balloting officers put a strip of paper along side each of the 16 > slots on the machine (or lesser, if the number of candidates is less > than 16). The voter pushes a button next to the slot with the name of > his candidate which records his/her vote for him. At the end of > polling, > the polling officer presses a button on the control unit, which shows the > total number of votes polled against each 'slot'. It is now the job of > the polling officers to take the machines to a tabulation center, > where the tabulation officers look at the names of candidates against > each slot and manually add up the votes from each polling station. > > 3. Thus the system, though technically a DRE does not preclude the > human role completely since tabulation of votes is done manually for > each DRE. It is not a fully automated system as an American Diebold. > > 4. Since each ballot unit can record only upto 3,840 votes, the chances that > a corrupt party can influence voting results by capturing a polling > booth (which is quite common here!) is vastly reduced, when compared > to the old papor balloting system. Once the polling officer has closed > a ballot station, the firmware is effectively untamperable. > > 5. Thuis the Indian e-voting systems are designed entirely different > when compared to American DREs. They are also much less complex with > no GUIs, > databases and associated software components. Hence chances of someone > actually tampering with the 'software' just before an election is much > less in an Indian election when compared to an American one. The only > way to tamper with an Indian DRE is to introduce malware into it right > at the production stage, when the code for the firmware is written. > This however is very unlikely since there are strict controls in > place. Of course, the second way to influence the voting results is to > influence the tabluation officers themselves so that votes are > incorrectly tabulated for a candidate.
