Por proofs of retrievability
WebSep 1, 2012 · In the proof of retrievability model, the prover consists of an arbitrary program as opposed to a simple memory layout and this program may answer these questions in an arbitrary manner. We believe that this realistically represents an adversary in the type of setting we are considering. WebOne of possible alternatives for useful Proof-of-Work schemes, Permacoin, is using non-interactive proofs of a static dataset retrievability thus providing a mechanism to store a huge dataset being spread across miners collectively. In this paper we present a new consensus protocol for Bitcoin-like peer-to-peer systems, where the right to ...

Webmodel for proofs of replication and retrievability. Our proposed model, PoR2, extends the POR model outlined in [34] and addresses security risks that have not been covered so far in existing multi-replica PDP models. • We describe a concrete PoR2 scheme, dubbed Mirror that is secure in our enhanced security model. Mirror leverages a tunable ... WebJan 18, 2024 · Proofs of Retrievability (PoR) protocols ensure that a client can fully retrieve a large outsourced file from an untrusted server. Good PoRs should have low communication complexity, small storage overhead and clear security guarantees with tight security bounds. The focus of this work is to design good PoR schemes with simple …
