Shuffle for Paillier's Encryption Scheme

摘要

In this paper, we propose a proof scheme of shuffle, which is an honest verifier zero-knowledge proof of knowledge such as the protocols by Groth and Furukawa. Unlike the previous schemes proposed by Furukawa-Sako, Groth, and Furukawa, our scheme can be used as the shuffle of the elements encrypted by Paillier's encryption scheme, which has an additive homomorphic property in the message part. The ElGamal encryption scheme used in the previous schemes does not have this property.
