Post-Quantum Succinct Arguments
Alessandro Chiesa and Fermi Ma and Nicholas Spooner and Mark Zhandry
Abstract
We prove that Kilian's four-message succinct argument system is post-quantum secure in the standard model when instantiated with any probabilistically checkable proof and any collapsing hash function (which in turn exist based on the post-quantum hardness of Learning with Errors). At the heart of our proof is a new "measure-and-repair" quantum rewinding procedure that achieves asymptotically optimal knowledge error.
