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.

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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
