Proxy Provable Data Possession with Key-exposure Resilient [PDF]
Jisuanji kexueMore and more clients would like to store their data to public cloud server along with the rapid development of cloud storage.To check the integrity of remote data,researchers proposed provable data possession(PDP).In some cases,the client will be ...

Online/Offline Provable Data Possession
IEEE Transactions on Information Forensics and Security, 2017 Provable data possession (PDP) allows a user to outsource data with a guarantee that the integrity can be efficiently verified. Existing publicly verifiable PDP schemes require the user to perform expensive computations, such as modular exponentiations for processing data before outsourcing to the storage server, which is not desirable for weak users ...

MR-PDP: Multiple-Replica Provable Data Possession [PDF]
2008 The 28th International Conference on Distributed Computing Systems, 2008 Many storage systems rely on replication to increase the availability and durability of data on untrusted storage systems. At present, such storage systems provide no strong evidence that multiple copies of the data are actually stored. Storage servers can collude to make it look like they are storing many copies of the data, whereas in reality they ...

Provable Dynamic Data Possession by Datalog Rules
Journal of Software, 2014 In recent years, the concept of data outsourcing has become quite popular. With the appearance of Cloud Computing, there is a new paradigm: Cloud Storage. Cloud Storage means that the data owner moves its data to a Cloud Storage Server that is supposed to faithfully store the data and make it available to the data owner and perhaps the data requestors.

An Effective Scheme for Provable Data Possession [PDF]
Proceedings of the 2016 International Conference on Intelligent Control and Computer Application, 2016 At present, almost all the provable data possession schemes require a large number of exponent calculations. In this paper a new scheme based on the homomorphy of NTRU algorithm is proposed. The scheme includes modules of Key Generation, Tag Generation, Challenge, Proof Generation, and Verification. This scheme requires only plus, minus, multiplication

Cryptographic Accumulator-Based Scheme for Critical Data Integrity Verification in Cloud Storage
IEEE Access, 2019 Public cloud storage is a fundamental cloud computing service. Currently, most owners of large data outsource their data to cloud storage services-even high-profile owners such as governments.

Certificateless public key cryptography based provable data possession scheme in edge environment
Tongxin xuebao, 2022 In the edge environment, data transmission to the cloud needs to pass through a new entity, the edge node, which makes the data security problem more complicated, the confidentiality and integrity of data are difficult to be guaranteed, and the ...

Certificateless Provable Data Possession Protocol for the Multiple Copies and Clouds Case
IEEE Access, 2020 For user's extremely important data, storing multiple copies on cloud(s) may be a good option because even if the integrity of one or more copies is broken, it can still recover data from other intact ones, which increases the availability and durability
