Abstract
In this paper, we propose a secure cloud storage service architecture with the focus on Data Integrity as a
Service (DIaaS) based on the principles of Service-Oriented Architecture and Web services. Our approach not only
releases the burdens of data integrity management from a storage service by handling it through an independent third party data Integrity Management Service (IMS), but also reduces the security risk of the data stored in the storage services by checking the data integrity with the help of IMS. We define data integrity protocols for a number of different scenarios, and demonstrate the feasibility of the proposed architecture, service and protocols by implementing them on a public cloud, Amazon S3. We also study the impact of our proposed protocols on the performance of the storage service and show that the benefits of our approach outweigh the little
penalty on the storage service performance
INTRODUCTION
Cloud computing is touted as the next generation of computing and considered to make significant advances in
the next decade. The driving forces behind cloud computing are: (a) significantly reduced Total Cost of Ownership (TCO) of the required IT infrastructure and software including (but not limited to) purchasing, operating, maintaining and updating costs; (b) high Quality of Service (QoS) provided by cloud service providers such as availability, reliability and Pay-As-You-Go (PAYG) based low prices; (c) easy access to organizational information and services anytime anywhere; and (d) dynamic resource scaling based on demand. In a nutshell, cloud computing provides a new paradigm for delivering computing resources to customers on demand in a similar fashion as utilities
