[en] We revisit the e-voting protocol IVXV that is used for legally-binding political elections in Estonia from a privacy perspective. We demonstrate that IVXV is vulnerable to attacks against vote privacy in those threat scenarios that were considered for IVXV originally. We explain how to improve IVXV so that it protects against the privacy issues we discovered.
