Proofs of Retrievability (POR) are cryptographic proofs which provide assurance to a single tenant (who creates tags using his secret material) that his files can be retrieved in their entirety. However, POR schemes completely ignore storage-efficiency concepts, such as multi-tenancy and data deduplication, which are being widely utilized by existing cloud storage providers. Namely, in deduplic...

Abstract—Cloud storage enables users to remotely store their data and enjoy the on-demand high quality cloud applications without the burden of local hardware and software management. Though the benefits are clear, such a service is also relinquishing users’ physical possession of their outsourced data, which inevitably poses new security risks towards the correctness of the data in cloud. In o...

Cloud computing allows for access to ubiquitous data storage and powerful computing resources through the use of web services. There are major concerns, however, with data security, reliability, and availability in the cloud. In this paper, we address these concerns by introducing a novel security mechanism for secure and fault-tolerant cloud information storage. The information storage model f...

To provide fault tolerance for cloud storage, recent studies propose to stripe data across multiple cloud vendors. However, if a cloud suffers from a permanent failure and loses all its data, then we need to repair the lost data from other surviving clouds to preserve data redundancy. We present a proxy-based system for multiple-cloud storage called NCCloud, which aims to achieve cost-effective...

Massive data storage is one of the great challenges for cloud computing service, and reliable storage of sensitive data directly affects quality of storage service. In this paper, based on analysis of data storage process in cloud environment, the cost of massive data storage is considered to be comprised of data storage price, data migration and communication; and the storage reliability consi...

Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources. Cloud computing provides computation, software, data access, and storage services that do not require end-user knowledge of the physical location and configuration of the system that delivers the services. Since the data transmission on the internet or over any netw...

Using Cloud computing user can store their data secure without load of local user computer. And this feature additionally should be cable enough to provide user to maintain the cloud storage, as it is if same is maintained in the local, where no consideration required verifying the data integrity. On top by enabling and having public audit for cloud storage, which cab check the integrity of dat...

Enterprise class architectures for cloud computing have begun to emerge, driven by recent advances in virtualization of servers, storage, and access networks. We present a hierarchy classification scheme for cloud services, based on whether the intrastructure, platform, or software is being provisioned and virtualized. We then discuss early adoption of public and private clouds based on the cli...

Using Cloud Storage, users can remotely store their data and enjoy the on-demand high quality applications and services from a shared pool of configurable computing resources, without the burden of local data storage and maintenance. However, the fact that users no longer have physical possession of the outsourced data makes the data integrity protection in Cloud Computing a formidable task. Un...
