A Verifiable Re-encryption Mix

Problem 3 The challenges for this re-encryption mix can be obtained by feeding all of the intermediate and final ballot sets into a cryptographic hash function such as SHA-1. The output bits of the hash can be used as the challenge bits in an interactive proof. 3/10/2011Practical Aspects of Modern Cryptography
