Towards secure and dependable storage service in cloud

AbstractCloud 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 order to address this new problem and further achieve a secure and dependable cloud storage service, we propose in this paper a flexible distributed storage integrity auditing mechanism, utilizing the homomorphic token and distributed erasure-coded data. The proposed design allows users to audit the cloud storage with very lightweight communication and computation cost. The auditing result not only ensures strong cloud storage correctness guarantee, but also simultaneously achieves fast data error localization, i. Considering the cloud data are dynamic in nature, the proposed design further supports secure and efficient dynamic operations on outsourced data, including block modification, deletion, and append.

Towards Secure and Dependable Storage Services in Cloud Computing

Many companies today are expanding into cloudcomputing as a way to reduce the cost and complexityof delivering traditional IT services. Cloud is not a particular product, but a way of delivering ITservicesthat are consumable on demand, elastic to scale up anddown as needed, and follow a pay-for- usage model. Cloud is an elastic delivery model that enables businesses tobecome more adaptable and interconnected. Monolithic andageing infrastructures give way or progress toward a rent versusbuy state of agility, where non-core competencies are shed fornot just on-demand technology, but also for on- demand businessinnovation and savings. Cloud is not a point product or a singulartechnology, but a way to deliver IT resources in a manner thatprovides self- service, on-demand and pay-per-use consumption.

Towards secure and dependable storage

Last but not the least, the deployment of Cloud Computing is powered by data centers running in a simultaneous, cooperated and distributed manner [3]. It is more advantages for individual users to store their data redundantly across multiple physical servers so as to reduce the data in- tegrity and availability threats. Thus, distributed proto- cols for storage correctness assurance will be of most importance in achieving robust and secure cloud storage systems. However, such important area remains to be fully explored in the literature.

Show all documents Data Leakage Detection and Dependable Storage Service In Cloud Computing The Data integrity is measured by MD5[6] by the help of bit message, that message is given by user to create a fingerprint message is of variable length; the main thing is that it is irreversible. The Father of this algorithm is Professor Ronald L. Rivets of MIT.
