Remote records integrity checking (RDIC) allows a statistics storage server, such as a cloud server, to demonstrate to a verifier that it is truly storing a data proprietor's data. To date, a number of RDIC protocols have been proposed in the literature, but the majority of the structures suffer from the issue of complicated key control, that is, they rely on the expensive public key infrastructure (PKI), which may prevent RDIC from being deployed in practice. In this paper, we propose a brand new identity-based totally (ID-based totally) RDIC protocol that makes use of key-homomorphic cryptographic primitives to reduce system complexity and the fee for establishing and managing the public key authentication framework in PKI-based totally RDIC schemes.

We formalize ID-based RDIC and its security model, which includes protection from a malicious cloud server and zero knowledge privacy from a third birthday celebration verifier. At some point during the RDIC process, the proposed ID-based completely RDIC protocol leaks no statistics of the saved statistics to the verifier. In the standard group version, the new construction is shown to be friendly to the malicious server and achieves zero expertise privacy against a verifier. Extensive security assessment and implementation results show that the proposed protocol is provably safe and realistic in real-world programs
