Data Security And Integrity Of Cloud StorageIn Cloud Computing

2013

Cloud computing is the computing paradigm which enable obtaining resources like software, hardware, services over the internet. Most of user store their data on cloud for data security and integrity are prime related. In this article the problem of ensuring data integrity and security of data storage in cloud computing. For ensuring correctness of data, we assume the task of allowing a Third party auditor(TPA) used for exposing risk of cloud storage services on behalf of the cloud client to verify data integrity stored in the cloud. This paper focus on the data security, we proposed erasure correcting code in the file distribution to provide the redundancies and guarantee data dependability. By using homomorphic token with distributed verification of erasure coded data ,our scheme achieve storage correctness as well as error localization. Extensive security analysis show the proposed scheme is highly efficient and resilient against Byzantine failure, malicious data alternation attac...

Storage Data Security of Data in Cloud Computing

Cloud Computing refers to the many different types of services and applications being delivered in the internet cloud, and the fact that, in many cases, the devices used to access these services and applications do not require any special applications. Cloud Computing has been moves the application software and databases to the centralized large data centers, where the management of the data and services may not be fully trustworthy. This brings the problem of ensuring the integrity of data storage in Cloud. Cloud computing share distributed resources via network in the open environment thus it makes security problem. we consider the task of allowing a third party auditor (TPA), on behalf of the cloud client, to verify the integrity of the dynamic data stored in the cloud. The introduction of TPA eliminates the involvement of the client through the auditing of whether his data stored in the cloud are indeed intact, which can be important in achieving economies of scale for Cloud Computing. The support for data dynamics via the most general forms of data operation, such as block modification, insertion, and deletion, is also a significant step toward practicality, since services in Cloud Computing are not limited to archive or backup data only. While prior works on ensuring remote data integrity often lacks the support of either public auditability or dynamic data operations, this paper achieves both. We first identify the difficulties and potential security problems of direct extensions with fully dynamic data updates from prior works and then show how to construct an elegant verification scheme for the seamless integration of these two salient features in our protocol design. In particular, to achieve efficient data dynamics, we improve the existing proof of storage models by manipulating the classic Merkle Hash Tree construction for block tag authentication.

Data Security for Cloud computing Storage System

Cloud computing is a forthcoming revolution in information technology industry because of its performance, accessibility, low cost and many other luxuries. It provides storage for data and faster computing to customers over the internet. That is why companies are reluctant to deploy their business in the cloud even cloud computing offers a wide range of luxuries. Security of data in the cloud is one of the major issues which acts as an obstacle in the implementation of cloud computing. Considering to the high storage capacity and also qualified personnel it becomes difficult pertaining the management of such huge amount of data. Some of the facilities like Storage-as-a-Service offered by cloud service providers help organizations to outsource their data to get saved on Remote servers. Thus, such services like Storage as a service helps in reducing the cost of maintenance and also helps to reduce the SaaS burden of large local data storage at the organization's perspective.

International Journal of Computer Applications, 2013

Cloud computing is emerging as a new technology in the field of computing which effects many aspects of computing. The users are enabled to move their data and application software to the network and access the services on-demand. Moving data outside the organizational boundaries and access them through internet makes complete loss of control from the owner's side. The data over the cloud servers is easily accessed by both the computing providers and law enforcement agencies easier in comparison to data stored on your local disk. Cloud brings many different security issues and among them data security acts as one of the major challenge in cloud computing. Data security becomes an important issue for securing outsourced data and to maintain a level of trust among data owners. In this paper we will analyze the security requirements and the various approaches for data security. We also highlight the new emerging research challenges in data security and privacy.

Security of Data Storage in Cloud Computing

International Journal of Computer Applications, 2015

With the advent of Information Technology in day-today activities, the need for online services such as storage space, software, platforms etc. is increasing rapidly. This lead to the rise of a new concept, the Cloud Computing. The Internet users rely heavily on the Cloud Computing for various computing resources. The main motive of the Cloud Providers is to provide these services in a virtualized manner. One of the main concern of cloud computing is the security of the Cloud Storage. When it comes to security of the data stored in the Cloud Storage, it is entirely in the hands of the Cloud Providers. The Cloud Providers assures the consumer of the Cloud that the data stored on their servers is safe. The consumer plays no role in securing the data. The various cloud providers claim that they provide highly secure cloud storage. But there have been attacks on hot-shot cloud providing companies such as Google, Salesforce.com and Dropbox[1]. Many cloud providers employee third party companies which has led to consumer losing their trust with these companies. Thus, the encryption techniques and the various security measures employed by the cloud providers should be equally strong. The privacy and security of cloud computing depend primarily on whether the provider has implement adequate and robust security controls as desired by the customer or not. In this paper we analyze the different security issues related to the cloud and different cryptographic algorithms to secure the cloud.
