Cloud Data Auditing Using Proofs of Retrievability

TL;DR

This paper discusses proofs of retrievability (POR) as a method for ensuring data integrity and retrievability in cloud storage, providing clients with guarantees against data tampering by cloud servers.

Contribution

It introduces the concept of proofs of retrievability (POR) for cloud data auditing, enhancing data integrity assurance in outsourced cloud storage.

Findings

POR schemes effectively verify data integrity.

Clients gain guarantees of untampered data.

Enhanced trust in cloud storage systems.

Abstract

Cloud servers offer data outsourcing facility to their clients. A client outsources her data without having any copy at her end. Therefore, she needs a guarantee that her data are not modified by the server which may be malicious. Data auditing is performed on the outsourced data to resolve this issue. Moreover, the client may want all her data to be stored untampered. In this chapter, we describe proofs of retrievability (POR) that convince the client about the integrity of all her data.
