Towards Secure and Dependable Storage Services in Cloud Computing (1)

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.

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. This algorithm is best for 32 bit and 16 bit machines the comp-ability of this algorithm can be extended to 64 bit machines also but this type of scheme may be quite slow because of its architecture. MD5 is the extension of MD4 algorithm which is quite faster because of its three rounds and MD5 contains four rounds which makes its slower. They contacted these users and helped them protect their accounts, the company wrote in a blog post today.

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. Cloud is designed to distribute IT resources in a cost-effectiveand nimble way.


Cloud storage enables users to remotely store their data and enjoy the on-​demand high quality cloud applications without the burden of local.

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.

Analysis shows the proposedscheme is highly efficient and resilient against Byzantine failure, malicious data modification attack, and even server colluding attacks.
