For electronic voting(e-voting)with a trusted authority,the ballots may be discarded or tampered,so it is attractive to eliminate the dependence on the trusted party.An e-voting protocol,where the final voting result can be calculated by any entity,is known as self-tallying e-voting protocol.To the best of our knowledge,addressing both abortive issue and adaptive issue simultaneously is still an open problem in self-tallying e-voting protocols.Combining Ethereum blockchain with cryptographic technologies,we present a decentralized self-tallying e-voting protocol.We solve the above problem efficiently by utilizing optimized Group Encryption Scheme and standard Ex-ponential ElGamal Cryptosystem.We use zero-knowledge proof and homomorphic encryption to protect votes'secre-cy and achieve self-tallying.All ballots can be verified by anyone and the final voting result can be calculated by any entity.In addition,using the paradigm of score voting and"1-out-of-k"proof,our e-voting system is suitable for a wide range of application scenarios.Experiments show that our protocol is more competitive and more suitable for large-scale voting.
