Presentation Outline
  • Introduction
  • What is e-voting?
  • Problem / Controversy
  • Security Issues
  • Social Issues
  • Conclusion
  • Proposed Solutions
  • Research Thesis

3
What is E-Voting?
  • E-voting is an election system that allows a
    voter to record his or her secure and secret
    ballot electronically.

4
DRE Voting System
  • A DRE machine directly records the voters
    selections in each contest, using a ballot that
    appears on a display screen.

5
Evolution of DREs
  • They are divided into 3 types
  • Similar to lever machines
  • Display type
  • Display type using touch screen

6
Controversies Problems
  • Voter Data Privacy/Security
  • System Vulnerable to Intrusion
  • Software Intrusion
  • Hardware Intrusion
  • No Verifiable Paper Trail

7
Security Issues of DREs
  • Attacks Divided into 2 groups
  • Vote Tampering
  • Multi-Cast
  • Vote Stealing
  • Denial-of-Service
  • Denied Access
  • Spoiled Data

8
Security Issues of DREs (cont.)
  • Common Exploits in Attack Patterns
  • Smartcard/Memory Card
  • Improper Handling/Securing of Data
  • Poor System Design

9
Vote Tampering
  • Gaining Access to the Machine
  • Duplicated or Stolen Smartcard
  • Reprogramming Flash Memory
  • Memory Card
  • Learn Protocol or Code Injection
  • Reverse Engineering Protocol
  • Computer Virus or Buffer Overflow

10
Denial-of-Service
  • Gaining Access to the Machine
  • Same as vote tampering
  • Crash System
  • Time/Date program trigger
  • Corrupt Vote Data
  • Same techniques as vote tampering

11
Social Issues of E-Voting
  • Why is it important?
  • It is equally important as the technical side.
  • Social aspects of e-voting is important because
    if in any election the machines do get hacked,
    they could trigger the elections and the outcome.
  • It is the way society thinks about e-voting.
  • People have started to be aware about the
    problem.

12
Social Issues of E-Voting (cont.)
  • Countries that use electronic voting machines
  • - USA, UK, France, Germany, Australia,
    Netherlands, India, Brazil, Switzerland, Spain,
    Portugal, Norway, Ireland, Estonia, Canada,
    Belgium, Austria.

13
Social Issues of E-Voting (cont.)
  • Since so many countries have invested into
    e-voting, they are hesitant to drop it and go
    back to paper ballots.
  • Its becoming more and more popular.
  • It is the direction we are heading to.

14
Possible Solutions
  • Some theoretical solutions.
  • Use open-source software
  • Use voter-verifiable paper ballot
  • Encrypted votes
  • Parallel testing
  • Legislation

15
Use Open-Source Software
  • Some experts believe that the code should be
    available for public inspection.
  • It will undergo thorough inspection.
  • Maybe, some security flaws can be fixed by this
    method.

16
Voter-Verifiable Paper Ballot
  • The computer would print a paper ballot.
  • Voter would then verify that the ballot
    accurately reflected the voters choice made on
    the DRE machine.
  • This way, no votes will be improperly changed.
  • Disadvantage Show your receipt that you voted
    for X candidate, and here is your free gift.

17
Encrypted Votes
  • Votes will be independently recorded on an
    independent machine other than the DRE.
  • This way a recount can be done to make sure the
    votes recorded on the DRE were accurate or not.
  • The recount will be faster than the paper ballot
    verification.

18
Parallel Testing
  • Parallel testing is when election officials take
    some DRE machines and set them aside during an
    election.
  • All day, they cast votes simultaneously and at
    the end of the day, they tally their votes.

19
Legislation
  • Funding for research to improve DRE machines.
  • Adding more requirements for the DRE machines in
    order for it to be used in elections.
  • Legislative solution may be more useful if
    controversy is not resolved by other means.

20
Our Own Solution
  • Because everything is so secret, no one really
    knows how they are implementing the solutions.
  • Since it is theoretical, there really isnt a
    significant solution to the problem.
  • OUR SOLUTION is to use the seven touchpoints of
    software security.

21
Conclusion
  • Should e-voting be used or not?
  • There are many advantages to e-voting but the
    problems with the systems overrule the
    advantages.
  • E-voting machines are unreliable.
  • Even with all the security problems there is a
    growing trend among countries to invest more into
    e-voting machines.

22
Conclusion
  • Ireland Stopped using them unless machines are
    upgraded.
  • France considering.
  • This could also be a trend about to begin.
  • Countries might start going back to paper
    ballots.
  • UNLESS WE FIX THE PROBLEMS RELATED TO E-VOTING
    MACHINES!
