Verifiable Shuffles: A Formal Model and a Paillier-based 3-Round Construction with Provable Security

Lan Nguyen and Rei Safavi-Naini and Kaoru Kurosawa

Abstract: We propose a formal model for security of verifiable shuffles and a new verifiable shuffle system based on the Paillier encryption scheme, and prove its security in the proposed model. The model is general, so it can be extended to verifiable shuffle decryption and provides a direction for provable security of mix-nets.
