In this paper, we define and explore proofs of retrievability (PORs). A POR scheme enables an archive or back-up service (prover) to produce a concise proof that a user (verifier...
Proofs of Retrievability (PoR), introduced by Juels and Kaliski [JK07], allow the client to store a file F on an untrusted server, and later run an efficient audit protocol in whi...
We are interested in this problem: a verifier, with a small and reliable storage, wants to periodically check whether a remote server is keeping a large file x. A dishonest server,...
