A note on replay attacks that violate privacy in electronic voting schemes
Ben Smyth, Véronique Cortier · 2011
In our previous work, we have shown that the Helios 2.0 electronic voting protocol does not satisfy ballot independence and exploit this weakness to violate privacy; in particular, the Helios scheme is shown to be vulnerable to a replay attack. In this note we examine two further electronic voting protocols -- namely, the schemes by Sako & Kilian and Schoenmakers -- that are known not to satisfy ballot independence and demonstrate replay attacks that violate privacy.
