Distributed data possession provable in cloud

Distributed and Parallel Databases, 2016
Nowadays, many organizations outsource their data to remote cloud servers. In order to increase the availability of data, the data owners store their data replicas on multiple servers. In this paper, we propose a dynamic replicated data possession checking scheme that has three characteristics: the data owner uses fully homomorphic encryption algorithm

Provable Data Possession in Cloud Computing

Applied Mechanics and Materials, 2014
Several trends are opening up the era of cloud computing. It 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 work studies the problem of ensuring the integrity of data storage in cloud computing.

An Efficient Provable Data Possession Scheme with Data Dynamics

2012 International Conference on Computer Science and Service System, 2012
Ateniese et al proposed an efficient Provable Data Possession scheme which uses only hash and symmetric-key cryptographic functions, but it cannot support block insertion. To achieve full data dynamics, a SN-BN table which maps the logical indices of blocks to their physical ones is introduced.

Identity-Based Batch Provable Data Possession

2016
Provable Data Possession PDP is a technique for checking whether data is correctly stored in remote servers without retrieving the entire data. For many previous PDP schemes, correctly choosing public key for clients relies on the security of Public Key Infrastructure PKI, but PKI itself still faces many kinds of security vulnerabilities.

Robust/Recover Provable Data Possession Protocol

2019
Provable data possession (PDP) allows a client that has stored data at remote server to verify that the server correctly possesses the original data. A long-standing problem is how to reduce I/O cost. Through the integration of Online-code and PDP, a challenge/check protocol that can verifies the possession is proposed.

Efficient provable data possession for hybrid clouds

Proceedings of the 17th ACM conference on Computer and communications security, 2010
Provable data possession is a technique for ensuring the integrity of data in outsourcing storage service. In this paper, we propose a cooperative provable data possession scheme in hybrid clouds to support scalability of service and data migration, in which we consider the existence of multiple cloud service providers to cooperatively store and ...

An improved dynamic provable data possession model

2011 IEEE International Conference on Cloud Computing and Intelligence Systems, 2011
Cloud computing is becoming increasingly popular. Many companies, organizations and individuals choose to outsource their computing demands and storage demands. In order to ensure the integrity of the data in the Cloud, especially the dynamic files which can be updated online, we propose an improved dynamic provable data possession model: It divides ...

Identity-Based Batch Provable Data Possession with Detailed Analyses

International Journal of Foundations of Computer Science, 2017
In the era of big data, cloud storages become prevalent while security issues on outsourced data emerge. Without the physical control of the data owners, the outsourced data faces more risks. Provable Data Possession (PDP) is a probabilistic technique for checking whether data is correctly stored in remote servers without retrieving the entire data ...

A Non-repudiable Dynamic Provable Data Possession

2019
With the widespread popularity of cloud storage, cloud storage security issues have also received much attention. A provable data possession (PDP) scheme can effectively help users to verify the integrity of data stored remotely in the cloud. For this reason, the client’s PDP scheme is constantly improving and developing.

Provable Data Possession Supporting Secure Data Transfer for Cloud Storage

2015 10th International Conference on Broadband and Wireless Computing, Communication and Applications (BWCCA), 2015
Due to the appealing advantages of cloud storage, such as on-demand self-service and ubiquitous network access, an increasing number of users prefer to store their data on remote remote servers. However, outsourced data transfer becomes a critical requirement for users to shift their cloud storage providers because of the emergence of various cloud ...
