Privacy Preservation in I-voting Using Homomorphic Technology

Voting is one of the most important activities in a democratic society. In a usual voting environment voting process sometimes becomes quite difficult due to the unwillingness of certain voters to visit a polling booth to cast votes besides involving huge social and human resources. The advance of computer networks and security techniques help the implementation of electronic voting. I-voting protocol is based on Homomorphic Technology and guarantees eligibility, unreusability, privacy, verifiability and also receipt-freeness and uncoercibility. The scheme can be implemented in a practical environment, since it does not use voting booth or untappable channel, only public channels are applied. The proposed protocol encompasses three distinct phases that of registration phase, voting phase and counting phase involving five parties, the voter, certification centre, authentication server, voting server and a tallying server.
