Efficient Data Recovery with Data Integrity Protection

By Nikolay Kyurkchiev, Anton Iliev, Asen Rahnev

To protect outsourced data in cloud storage against corruptions, enabling integrity protection, fault tolerance, and efficient recovery for cloud storage becomes critical. FMSR-DIP is a proof-of-concept prototype aimed at providing data integrity protection atop today's cloud storage. FMSR-DIP augments the FMSR code with a data checking capability that allows stored data to be sampled for checking in a flexible manner, without adding to its download traffic requirements during file downloads or repairs. So its provides an efficient data integrity checking capability to FMSR code to provide a more comprehensive data protection solution, without eliminating the advantage of using FMSR code.We design and implement a practical data integrity protection (DIP) scheme for a specific regenerating code, while preserving the intrinsic properties of fault tolerance and repair traffic saving. This DIP scheme is designed under a Byzantine adversarial model, and enables a client to feasibly verify the integrity of random subsets of outsourced data against general or malicious corruptions.
