    Long-term Retention in E-Voting – Legal Requirements and Technical Implementation
    (Electronic Voting 2008 (EVOTE08). 3rd International Conference on Electronic Voting 2008, Co-organized by Council of Europe, Gesellschaft für Informatik and EVoting.CC, 2008) Gitter, Rotraud; Langer, Lucie; Okunick, Susanne; Opitz-Talidou, Zoi
    Legally binding elections require retention of specified election data such as balloting material. This applies to paper-based as well as electronic elections. However, in Germany, legal requirements on retention in e-voting have not been issued so far. Based on the German legal framework for governmental as well as non-governmental paper-based elections, we give recommendations on long-term retention in e-voting, applying our results to a state-of-the-art e-voting scheme. We also review technical measures to meet the security requirements of long-term retention in e-voting.

    A pervasively verifiable online voting scheme
    (INFORMATIK 2008. Beherrschbare Systeme – dank Informatik. Band 1, 2008) Langer, Lucie; Schmidt, Axel; Araújo, Roberto
    We present an improvement of Ohkubo et al.’s e-voting protocol [OMA+99]: We provide that the validator’s signature is attached directly to the vote although the vote has been encrypted before. Thus verifiability does not end before tallying like in the original scheme but is pervasive even beyond the end of the election. This prevents manipulation of the plaintext votes and offers verifiability to the public instead of restricting it to the talliers. Moreover, privacy can be ensured without using blind signatures, which facilitates receipt-freeness. Our variant of the scheme also allows the voter to seemingly comply with the demand of a coercer while actually casting the vote she intended.
