Provable Data Possession with Outsourced Data Transfer

IEEE Transactions on Services Computing, 2021
With the rapid development of cloud computing, more and more enterprises would like to upload and store their data in the public cloud. When the parts of the business of an enterprise are purchased by another enterprise, the corresponding data will be transferred to the acquiring enterprise.

Scalable and efficient provable data possession

Proceedings of the 4th international conference on Security and privacy in communication netowrks, 2008
Storage outsourcing is a rising trend which prompts a number of interesting security issues, many of which have been extensively investigated in the past. However, Provable Data Possession (PDP) is a topic that has only recently appeared in the research literature.

Provably Secure Identity Based Provable Data Possession

2015
Provable Data Possession PDP, which enables cloud users to verify the integrity of their outsourced data without retrieving the entire file from cloud servers, is highly essential in secure cloud storage. A majority of the existing PDP schemes rely on the expensive Public Key Infrastructure PKI.

Blockchain-Based Private Provable Data Possession

IEEE Transactions on Dependable and Secure Computing, 2019
Remote data secure storage is of crucial importance in cloud computing. In order to check remote data integrity, an important paradigm PDP (i.e., provable data possession) is proposed. All the existing PDP schemes make use of RSA or bilinear pairings. One large file has to be divided into a great many of blocks. For example, 1T (Terabit) file has to be

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.

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.

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 ...

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 ...

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.
