Zero Knowledge Proofs for Database Authorization Rules

By AANSC Cryptography & Computing Group

Abstract

We construct mathematically verified proofs for validating row level access permissions on encrypted SQL columns without revealing metadata profiles.

Methodology

By integrating zk SNARK constraints directly into query planning compilation, we enable database systems to verify role access parameters while keeping enclaves blinded to active keys.
