Non-Interactive Batch Arguments for NP from Standard Assumptions
Arka Rai Choudhuri, Abhishek Jain, and Zhengzhong Jin
Abstract
We study the problem of designing *non-interactive batch arguments* for $\mathsf{NP}$. Such an argument system allows an efficient prover to prove multiple $\mathsf{NP}$ statements, with size smaller than the combined witness length. We provide the first construction of such an argument system for $\mathsf{NP}$ in the common reference string model based on standard cryptographic assumptions. Prior works either require non-standard assumptions (or the random oracle model) or can only support private verification. At the heart of our result is a new *dual mode* interactive batch argument system for $\mathsf{NP}$. We show how to apply the correlation-intractability framework for Fiat-Shamir -- that has primarily been applied to proof systems -- to such interactive arguments.
