Towards Trustworthy e-Voting using Paper Receipts

Yunho Lee and Kwangwoo Lee and Seungjoo Kim and Dongho Won

Abstract: Current electronic voting systems are not sufficient to satisfy trustworthy elections as they do not provide any proofs or confirming evidences of their honesty. This lack of trustworthiness is the main reason why e-voting is not widely spread even though e-voting is expected to be more efficient than the current plain paper voting. Many experts believe that the only way to assure voters that their intended votes are casted is to use paper receipts. In this paper, we propose an efficient scheme for issuing receipts to voters in e-voting using the well-known divide-and-choose method. Our scheme does not require any special printers or scanners, nor frequent observations to voting machines. In addition to that, our scheme is more secure than the previous ones.
