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.

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.

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.

Privacy Preserving Public Auditing and Data Integrity for Secure Cloud Storage Using Third Party Auditor

2016

Using cloud services, anyone can remotely store their data and can have the on-demand high quality applications and services from a shared pool of computing resources, without the burden of local data storage and maintenance. Cloud is a commonplace for storing data as well as sharing of that data. However, preserving the privacy and maintaining integrity of data during public auditing remains to be an open challenge. In this paper, we introducing a third party auditor (TPA), which will keep track of all the files along with their integrity. The task of TPA is to verify the data, so that the user will be worry-free. Verification of data is done on the aggregate authenticators sent by the user and Cloud Service Provider (CSP). For this, we propose a secure cloud storage system which supports privacy-preserving public auditing and blockless data verification over the cloud.

Implementation On Privacy-Preserving Public Auditing for Shared Data in the Cloud

In cloud computing, the way that organizations manage their data, due to its low cost and ubiquitous nature. Users access the application and enjoy the on-demand high quality information's and services from a shared pool of configurable computing resources, without the burden of local data storage and maintenance. This paper introduces a cloud database storage architecture, this approach prevents the risk of both external and internal attack to the outsourced data. 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. 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. Enhanced and secured third-party auditing, the auditing process should bring in no new vulnerabilities towards 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. furthermore, TPA is trusted and capable of accessing the cloud storage to performed auditing. 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. Our preliminary experiment conducted on Amazon EC2 instance further demonstrates 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

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.

A Comprehensive Survey on Public Auditing for Secure Cloud Storage

International Journal of Engineering & Technology

Cloud computing is the most popular paradigms used today by Industries & individual users to store data. This outsourcing releases user from capital as well as maintenance cost to own their data. But it brings new security challenges such as data integrity & privacy since user has no power of control on his own data. Advances in encryption & authentication techniques has improved security of data at cloud server(CS) but still it is not providing any certificate or assurance about cloud data to user. Most of the times users are not aware of the different controls employed by CS to protect integrity of data. Due to this lack of transparency in system, the user may lose trust on CS. Hence it is a need of user to check integrity of his data at regular intervals. Most of the researchers have given solutions to this problem with the help of cryptography techniques. External parties such as Third-Party Auditors (TPA) are performing audit to verify this remote data on behalf of user. This p...
