Proofs of Retrievability (POR) are cryptographic proofs which provide assurance to a single tenant (who creates tags using his secret material) that his files can be retrieved in their entirety. Howev...

Cloud storage allows clients to store a large amount of data with the help of storage service providers (SSPs). Proof-of-retrievability(POR) protocols allow one server to prove to a verifier the avail...

Proofs of Retrievability (PoR), introduced by Juels and Kaliski [JK07], allow the client to
store a le F on an untrusted server, and later run an ecient audit protocol in which the
server proves t...
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 lo...
In a proof-of-retrievability system, a data storage center must prove to a verifier that he is
actually storing all of a client's data. The central challenge is to build systems that are both
ecien...
