Por proofs of retrievability

WebA proof of retrievability (POR) [1] is a cryptographic proof technique for a storage provider to prove that clients’ data remain intact. In other words, the clients can fully retrieve their data and have confidence to use the recovered data. This highlights a strong need to seek an effective solution for checking whether WebGitHub - tgrafena/proof_of_retrievability: This is an approach for proofs of retrievability using a merkle tree as datastructure and chameleon hashes for updating the data. …
