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.
