Abstract-In this paper, we propose a dynamic audit service for verifying the integrity of an untrusted and outsourced storage. Our audit service is constructed based on the techniques, fragment structure, random sampling, and index-hash table, supporting provable updates to outsourced data and timely anomaly detection. In addition, we propose a method based on probabilistic query and periodic verification for improving the performance of audit services. Our experimental results not only validate the effectiveness of our approaches, but also show our audit system verifies the integrity with lower computation overhead and requiring less extra storage for audit metadata.

Abstract-A hybrid cloud is a cloud computing environment in which an organization provides and manages some internal resources and the others provided externally. However, this new environment could bring irretrievable losses to the clients due to lack of integrity verification mechanism for distributed data outsourcing. In this paper, we address the construction of a collaborative integrity verification mechanism in hybrid clouds to support the scalable service and data migration, in which we consider the existence of multiple cloud service providers to collaboratively store and maintain the clients' data. We propose a collaborative provable data possession scheme adopting the techniques of homomorphic verifiable responses and hash index hierarchy. In addition, we articulate the performance optimization mechanisms for our scheme and prove the security of our scheme based on multi-prover zero-knowledge proof system, which can satisfy the properties of completeness, knowledge soundness, and zero-knowledge. Our experiments also show that our proposed solution only incurs a small constant amount of communications overhead.

“…For cloud computing scenario, the traditional cryptographic techniques do not work for ensuring data integrity. Without having local copy such schemes [4], [5] and [6] do not work and thus cannot provide a practical solution. As the communications become expensive, the traditional approaches can't be applied to outsourced data to cloud.…”

Cloud computing technology enables data owners to outsource data and relieve from the burden of maintaining computing resources. This is possible as cloud provides platform independent, location independent, scalable and low-cost storage services. With virtualization technology, the cloud computing is made affordable. However, when data owners do not have physical possession of data, they need rely on security of cloud service providers completely. Integrity of their data is an important concern. Audit services that can ensure data integrity are essential. Many techniques came into existence in the recent past. Recently Zhu et al. presented Provable Data Possession (PDP) based interactive protocol for ensuring integrity of outsourced data. Based on this technique, in this paper we built a prototype application that demonstrates the proof of concept. The proposed application simulates the cloud environment where the audit service is provided for data integrity. The empirical results reveal that the application provides secure access to cloud services and provide data integrity.
