This paper discusses this cryptographic protocol, and in particular the ballot submission phase.
The security of the protocol relies on a novel hardness assumption similar to Decision Diffie-Hellman. While DDH is a claim that a random subgroup of a non-cyclic group is indistinguishable from the whole group, our assumption is related to the indistinguishability of certain special subgroups. We discuss this question in some detail.Category / Keywords: cryptographic protocols / Decision Diffie-Hellman, electronic voting Date: received 1 Aug 2013, last revised 9 Aug 2013 Contact author: kristian gjosteen at math ntnu no Available format(s): PDF | BibTeX Citation Note: The definition of B-privacy was wrong, it has been corrected.
