| Abstract(in English) | Other than performing integrity verification at untrusted stores, support for data dynamics is a critical component in the construction of Proofs of Data Possession (PDP) schemes for them to achieve practical applications in real life scenarios. We therefore propose the design of a fully dynamic storage protocol that additionally imposes a strong economical incentive to a cloud provider to store data in a particular format as desired by the client. The client or TPA can remotely verify the data an unlimited number of times with the additional capability of supporting data dynamics that includes data insertion, an important component missing in many PDP protocols. In particular, we present a permutation-like hourglass scheme that involves no cryptographic operations and whose security depends on the performance characteristics of the rotational drives and extend this scheme to a fully dynamic PDP scheme whose security analysis is shown to be provably secure and highly efficient. |
