In this project we propose an anonymous voting protocol that conceals the vote of each participant from all other participants (except the contestant voted for), and design an e-voting system that implements this protocol for leader elections. A public key encryption system is used to ensure anonymity of votes, and a zero-knowledge proof system is used to ensure verifiability of results.
Our system is compared against a non-anonymous baseline, to determine the costs involved in en- suring anonymity and verifiability. We also propose an alternate solution that uses a homomorphic encryption system and guarantees more anonymity, but do not discuss any implementation details.
