Leakage-resilient identification schemes from zero-knowledge proofs of storage

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

We provide a framework for constructing leakage-resilient identification (ID) protocols in the bounded retrieval model (BRM) from proofs of storage (PoS) that hide partial information about the file. More precisely, we describe a generic transformation from any zero-knowledge PoS to a leakage-resilient ID protocol in the BRM. We then describe a ZK-PoS based on RSA which, under our transformation, yields the first ID protocol in the BRM based on RSA (in the ROM). The resulting protocol relies on a different computational assumption and is more efficient than previously-known constructions.
