Abstract: 

We present Zeus, a verifiable internet ballot casting and counting system based on Helios, in which encrypted votes are posted eponymously to a server, then are anonymized via cryptographic mixing, and finally are decrypted using multiple trustee keys. Zeus refines the original Helios workflow to address a variety of practical issues, such as usability, parallelization, varying election types, and tallying through a separate computing system. In rough numbers, in the first nine months of deployment, Zeus has been used in 60 elections, tallying a total of more than 12000 votes.
