Efficient Receipt-Free Voting Based on Homomorphic Encryption
Voting schemes that provide receipt-freeness prevent voters from proving their cast vote, and hence thwart vote-buying and coercion. We analyze the security of the multi-authority ...

Verifiable Rotation of Homomorphic Encryptions
Similar to verifiable shuffling (or, mixing), we consider the problem of verifiable rotating (and random re-encrypting) a given list of homomorphic encryptions. The offset by which...
