Optimally Secure and Verifiable Election Scheme

• Robustness

  • Two types of faulty voters
    • Those who do not cast valid votes
      • Can be caught at validity checking step
  • Those who may try to prevent the tally from being correctly computed
  • An election protocol is optimally robust if the non-faulty voters can securely compute their tally successfully regardless of the number of faulty or dishonest voters.
  • Each party may become faulty or dishonest in a dynamic fashion
