We describe the theory behind a practical voting scheme based on homomorphic encryption. We give an example of an ElGamal-style encryption scheme, which can be used as the underlying cryptosystem. Then, we present efficient honest verifier zero-knowledge proofs that make the messages in the voting scheme shorter and easier to compute and verify, for voters(More)
We give suggestions for protection against adversaries with access to the voter’s equipment in voting schemes based on homomorphic encryption. Assuming an adversary has complete knowledge of the contents and computations taking place on the client machine we protect the voter’s privacy in a way so that the adversary has no knowledge about the voter’s(More)
