Guaranteeing Correctness of Bulk Operations in Outsourced Databases

Abstract : The adoption of public cloud services, as well as other data outsourcing solutions, raises concerns about confidentiality and integrity of information managed by a third party. By focusing on data integrity, we propose a novel protocol that allows cloud customers to verify the correctness of results produced by key-value databases. The protocol is designed for supporting efficient insertion and retrieval of large sets of data through bulk operations in read and append-only workloads. In these contexts, the proposed protocol improves state-of-the-art by reducing network overheads thanks to an original combination of aggregate bilinear map signatures and extractable collision resistant hash functions.
