Secure Cloud StorageForPrivacy-Preserving Public Audit
In Cloud Environment, using cloud storage service, users can remotely store their data and enjoy the on-demand high-quality applications and services from a shared pool of configurable computing resources, without the burden of local data storage and maintenance. However, the fact that users no longer have physical possession of the outsourced data makes the data integrity protection in cloud computing a formidable task, especially for users with constrained computing resources. Moreover, users should be able to just use the cloud storage as if it is local, without worrying about the need to verify its integrity. Thus, enabling public auditability for cloud storage is of critical importance so that users can resort to a third-party auditor (TPA) to check the integrity of outsourced data and be worry free. To securely introduce an effective TPA, the auditing process should bring in no new vulnerabilities toward user data privacy, and introduce no additional online burden to user. In this paper, we propose a secure cloud storage system supporting privacy-preserving public auditing. We further extend our result to enable the TPA to perform audits for multiple users simultaneously and efficiently. Extensive security and performance analysis show the proposed schemes are provably secure and highly efficient.
Cloud computing is internet based computing which enables sharing of services. Many users place their data in the cloud. However, the fact that users no longer have physical possession of the possibly large size of outsourced data makes the data integrity protection in cloud computing a very challenging and potentially formidable task, especially for users with constrained computing resources and capabilities. So correctness of data and security is a prime concern. This paper studies the problem of ensuring the integrity and security of data storage in Cloud Computing. Security in cloud is achieved by signing the data block before sending to the cloud. Using Cloud Storage, users can remotely store their data and enjoy the on-demand high quality applications and services from a shared pool of configurable computing resources, without the burden of local data storage and maintenance. However, the fact that users no longer have physical possession of the outsourced data makes the data integrity protection in Cloud Computing a formidable task, especially for users with constrained computing resources.
Third Party Public Auditing Scheme for Security in Cloud Storage
International Journal of Trend in Scientific Research and Development
By means of cloud storage, users can distantly store their data and enjoy the on-demand high-quality applications and services from a shared group of configurable computing resources, without the burden of local data storage and maintenance. However, the information that users no longer have physical ownership of the outsourced data makes the data integrity protection in cloud computing a difficult task, particularly for users with constrained computing resources. Moreover, users should be able to just use the cloud storage space as if it is local, without worrying about the need to verify its integrity. Thus, to enable public auditability for cloud storage is of serious importance so that users can rely on a third-party auditor (TPA) to verify the integrity of outsourced data and be worry free. To securely introduce a well-organized TPA, the auditing process should bring in no new vulnerabilities to user data privacy, and introduce no additional online burden to user. However; we propose a secure cloud storage system supporting privacy-preserving public auditing and monitoring. We additional would extend our result to enable the TPA to perform audits for multiple users simultaneously and efficiently, also integrity of data in cloud. Extensive security and performance analysis show the future schemes are provably secure and highly well-organized. Our beginning tryouts would be conducted on Amazon EC2 instance additional demonstrating the fast performance of the design.

SECURE SHARING AND AUDITING OF PRIVATE DATA IN PUBLIC CLOUD
IJRCAR, 2015
The advantages of storing important data in cloud storage are cost effective by use of shared computing resources and low infrastructure costs and high availability. However, users is not aware with physical structure and location of the outsourced data, it makes the data integrity protection in cloud computing a challenging task, especially for users with limited computing resources. Moreover, users should be able to access cloud storage as if it is local disk storage, without worrying about the need to verify its integrity. Thus, provide auditability for cloud storage is very important, so that users can ask to a third-party auditor (TPA) to check the integrity of outsourced data and use without worried. To create a secure and effective TPA, the auditing process should not allowed any new vulnerabilities toward user data privacy, and introduce no additional online overheads to user. In this paper, we propose a secure cloud storage system that supports privacy-preserving public auditing. We allow TPA to perform audits for multiple users simultaneously and efficiently. Extensive security and performance analysis show the proposed schemes are provably secure and highly efficient

Implementation of Public Auditing for Privacy Preserving in Secure Cloud Storage
Cloud computing area provides solution to the problem of limited storage using which a user can remotely store his or her data and enjoy the on demand high quality applications and services from a shared pool of configurable computing resources without handling the burden of local data that is being stored and maintained but the major fact is a user no longer possess the outsourced data that makes the data integrity protection in cloud computing environment as a formidable task for the users who posses constrained computing resources which pretends to use the cloud storage as if it is local without worrying about the need to verifying the data integrity by enabling public audit ability for cloud storage as it is considered to be critical where a user can resort to a third party auditor (TPA) to check the integrity of the outsourced data and be worry free. The vulnerabilities toward user data privacy introduce no additional online burden to user and in this paper we propose a secure cloud storage system that supports privacy preserving public auditing technique which is further extended to perform audits for multiple users simultaneously and efficiently by implementing extensive security and performance analysis which is proved in the proposed scheme which is provably secure and highly efficient.
Rigorous Public Auditing Support On Shared Data Stored In The Cloud By Privacy-Preserving Mechanism
2015
Cloud storage systems allow data owners to host their data on cloud servers and users (data consumers) can access their data from cloud servers. The paradigm of data hosting service also introduces new security challenges, which requires an independent auditing service to check the data integrity in the cloud server. Generally security in cloud is achieved by signing the data block before sending to the cloud server. Moreover, users should use cloud storage like the local storage and they didn't worry about the integrity of the data. In large-scale cloud storage systems, the data may be updated dynamically, so existing remote integrity checking methods served for static archive data are no longer applicable to check the data integrity. Thus, efficient and secure dynamic auditing protocols desired to convince data owners that the data is correctly stored in the cloud. The public auditability for cloud data storage security is of critical importance so that users can resort to an external audit party to check the integrity of stored data when needed. To securely introduce an effective third party auditor (TPA), these are : 1) TPA should be able to efficiently audit the cloud data storage without demanding the local copy of data, and introduce no additional on-line burden to the cloud user; 2) The third party auditing process should bring in no new vulnerabilities towards user data privacy. In this paper, we propose a secure cloud storage system supporting privacy-preserving and public auditing.
Effective Privacy-Preserving Public Auditing for Data Sharing in Cloud

Cloud computing represents today's most surprising computing paradigm shift in information technology. Without taking burden of local data storage and maintenance by using cloud storage, users can remotely store their data and enjoy the on-demand high quality applications and services from a shared pool of configurable computing resources. Most primary obstacles to its wide adoption are security and privacy. Shorter physical possession of the outsourced data of users makes the data integrity protection in Cloud. If the cloud storage is local then users should be able to just use it, without worrying about the need to verify its integrity. Enabling public auditability for cloud storage is of critical importance so that users can resort to a third party auditor (TPA) to check the integrity of outsourced data and be worry-free. To introduce an effective TPA with security the auditing process should brings it with no new vulnerabilities towards user data privacy and also introduces ...
Privacy-preserving public auditing for data storage security in cloud computing
… , 2010 Proceedings IEEE, 2010
Cloud Computing is the long dreamed vision of computing as a utility, where users can remotely store their data into the cloud so as to enjoy the on-demand high quality applications and services from a shared pool of configurable computing resources. By data outsourcing, users can be relieved from the burden of local data storage and maintenance. However, the fact that users no longer have physical possession of the possibly large size of outsourced data makes the data integrity protection in Cloud Computing a very challenging and potentially formidable task, especially for users with constrained computing resources and capabilities. Thus, enabling public auditability for cloud data storage security is of critical importance so that users can resort to an external audit party to check the integrity of outsourced data when needed. To securely introduce an effective third party auditor (TPA), the following two fundamental requirements have to be met: 1) TPA should be able to efficiently audit the cloud data storage without demanding the local copy of data, and introduce no additional on-line burden to the cloud user; 2) The third party auditing process should bring in no new vulnerabilities towards user data privacy. In this paper, we utilize the public key based homomorphic authenticator and uniquely integrate it with random mask technique to achieve a privacy-preserving public auditing system for cloud data storage security while keeping all above requirements in mind. To support efficient handling of multiple auditing tasks, we further explore the technique of bilinear aggregate signature to extend our main result into a multi-user setting, where TPA can perform multiple auditing tasks simultaneously. Extensive security and performance analysis shows the proposed schemes are provably secure and highly efficient.
