Privacy-preserving collaborative E-voting

Abstract

We propose a cooperative multi-party system where unrelated entities can both both vote and change their vote with continual accurate tabulation results while retaining vote privacy. The voting protocol presented uses homomorphic encryption, digital envelopes, Hamming weights, multiple parties to fulfill the needs of an e-voting system. The protocol is presented and limitations are explored. © 2008 Springer-Verlag Berlin Heidelberg.
