When outsourcing large sets of data to the cloud, it is desirable for clients to efficiently check,
whether all outsourced data is still retrievable at any later point in time without requiring to …

Proofs of retrievability (POR) are interactive protocols that allow a verifier to check the
consistent existence and availability of data residing at a potentially untrusted storage …

There has been considerable recent interest in “cloud storage” wherein a user asks a server
to store a large file. One issue is whether the user can verify that the server is actually storing …

Abstract 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 …

Cloud storage has gained increasing attention from the industry and research communities
with concerns about data stored in cloud computing environments, despite its many …

Locally correctable codes (LCCs) were introduced in order to retrieve pieces of information
from a noisy codeword, by using a limited number of queries to its symbols, this number …

Data loss is perceived as one of the major threats for cloud storage. Consequently, the
security community developed several challenge-response protocols that allow a user to …

This thesis deals with the security of the storage, the access and themaintenance of
outsourced data. Indeed, outsourced storage raises newthreats for users. We focus on the …

Abstract 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 …

In this paper, we show how to construct–from any linear code–a Proof of Retrievability
(𝖯𝗈𝖱) which features very low computation complexity on both the client (𝖵𝖾𝗋𝗂𝖿𝗂𝖾𝗋) and …
