Current Trusted Platform Modules (TPMs) are illsuited for use in mobile services because they hinder sharing data across multiple devices seamlessly, they lack access to a trusted real-time clock, and their nonvolatile storage performs poorly. This paper presents cloud TPM (cTPM), an extension of the TPM’s design to address these problems. cTPM includes two features: 1) a cloud seed shared betw...

Cloud storage enables users to access their data anywhere and at any time. It achieves the dream of getting computing, storage and communication resources as easy as to get water and electricity. All resources can be gotten in a plug-and-play way. It has the advantages of high scalability, ease-of-use, cost-effectiveness and simplifying infrastructure planning etc. However, the emerging use of ...

The LOCKSS system is a leading technology in the field of Distributed Digital Preservation. Libraries run LOCKSS boxes to collect and preserve content published on the Web in PC servers with local disk storage. They form nodes in a network that continually audits their content and repairs any damage. Libraries wondered whether they could use cloud storage for their LOCKSS boxes instead of local...

The secure deletion of data is of increasing importance to individuals, corporations as well as governments. Recent data breaches as well as advances in laws and regulations show that secure deletion is becoming a requirement in many areas. However, this requirement is rarely considered in today’s cloud storage services. The reason is that the established processes for secure deletion of on-sit...

With the advent of the big data era, cloud data storage and retrieval have become popular for efficient data management in large companies and organizations, thus they can enjoy the on-demand high-quality cloud storage service. Meanwhile, for security reasons, those companies and organizations would like to verify the integrity of their data once storing it in the cloud. To address this issue, ...

The emergence of the cloud storage as infrastructure for serving large amounts of data over the WAN suggests new storage/compute paradigms. We propose expanding the cloud storage from only storing data to directly producing value from the data by executing computational modules storlets close to where the data is stored. This paper describes the Storlet Engine, an engine to support computations...

Cloud Structure delivers infrastructure, platform and software as a service which are made available in pay-as-you go model. Cloud storage is a model of networked online storage where data is stored in virtualized pools of storage which are generally hosted by third parties. Users interact with the cloud servers through Cloud Storage Providers (CSP) to access or retrieve the data. Users have no...

Cloud architectures are moving away from a traditional data center design with SAN and NAS attached storage to a more flexible solution based on virtual machines with NAS attached storage. While VM storage based on NAS is ideal to meet the high scale, low cost, and manageability requirements of the cloud, it significantly alters the I/O profile for which NAS storage is designed. In this paper, ...
