Proofs of space were originally proposed as an alternative to the computation-based puzzles in blockchains and anti-abuse mechanisms [4,14], and require verifiable storage of a large amount of essentially-random data. A PoRep scheme (sometimes called Proof of Data Reliability) aims ...
WebNov 13, 2009 · A proof of retrievability (POR) is a compact proof by a file system (prover) to a client (verifier) that a target file F is intact, in the sense that the client can fully recover it. As PORs incur lower communication complexity than transmission of F itself, they are an attractive building block for high-assurance remote storage systems.

As... WebNov 10, 2024 · Proofs of Retrievability (PoR) are cryptographic protocols whose goal is to guarantee that a file stored by a client on a server remains retrievable in full. PoRs thus involve two parties: a client who owns a file F and a server, here modelled as an SMR, on which F is stored. We use the CC based definition of PoR security as presented in [ 1 ].
WebAs a transparent layer enforcing strong integrity guarantees, Iris lets an enterprise tenant maintain a large file system in the cloud. In Iris, tenants obtain strong assurance not just on data integrity, but also on data freshness, as well as data retrievability in case of accidental or adversarial cloud failures.
WebJul 1, 2013 · Our first scheme, built from BLS signatures and secure in the random oracle model, features a proof-of-retrievability protocol in which the client's query and server's response are both extremely short.
