Efficient permutation protocol for MPC in the head
Abstract
The MPC-in-the-head construction (Ishai et al., STOC'07) give zero-knowledge proofs from secure multiparty computation (MPC) protocols. This paper presents an efficient MPC protocol for permuting a vector of values, making use of the relaxed communication model that can be handled by the MPC-in-the-head construction. Our construction allows more efficient ZK proofs for relations expressed in the Random Access Machine (RAM) model. As a standalone application of our construction, we present batch anonymizable ring signatures.
