“…Even if behaving in a stable way, it is conceivable that untrusted users may cheat, by erasing the data they are supposed to store: to avoid this problem, provable data possession protocols exist [23,24]: these protocols allow to verify whether a given peer is actually holding the data it is claiming to store. In addition, game-theoretic incentive models [25,26] have been devised to encourage peers to participate to the network according to the protocol: users who do not behave fairly will lose their backup.…”

a b s t r a c tWe design and analyze the performance of a redundancy management mechanism for peer-to-peer backup applications. Armed with the realization that a backup system has peculiar requirements -namely, data is read over the network only during restore processes caused by data loss -redundancy management targets data durability, i.e. guaranteeing that data is not lost, rather than attempting to make each piece of information available at any time.In our approach each peer determines, in an on-line manner, an amount of redundancy sufficient to counter the effects of peer deaths, while preserving acceptable data restore times. Our experiments, based on trace-driven simulations, indicate that our mechanism can reduce the redundancy by a factor between two and three with respect to redundancy policies aiming for data availability. These results imply an according increase in storage capacity and decrease in time to complete backups, at the expense of longer times required to restore data. We believe this is a very reasonable price to pay, given the nature of the application.We complete our work with a discussion on practical issues, and their solutions, related to which encoding technique is more suitable to support our scheme.

Cloud storage provides service to the user for storing and maintaining their data. The users can access their data from anywhere, independent of location and provides less storage and maintenance cost. As the cloud is unreliable so this data storage service introduces security challenges, such as Confidentiality, Integrity, Availability and Reliability of data. In this paper we propose a new approach which is based on EEMSR (Explicit Exact Minimal Storage Regenerating Code) with hash function which provides Reliability, Availability as well as Integrity. An EMSR code which is a Regenerating code, can exactly regenerate back a lost block with less repair traffic. An EMSR code is defined by the parameters (n, k, d) that permits data recovery from any k of n nodes, and also have the capability of repairing a failed node by connecting to any d nodes. We used hash function with EMSR to achieve Integrity of the data stored in cloud through Challenge-Response protocol.

“…A lot of researchers have worked on the issue of remote verification of integrity in the storage mechanism adopted by cloud, all them have focused on different scenario of applications and tried to attain various objectives [4][5][6][7][8][9][10][11][12][13][14]. A model to ensure the control of data files in an environment which is not trustworthy is proposed by researcher and is known is provable data possession [6,10].…”

Cloud computing is a new paradigm of computing and is considered to be the next generation of information technology infrastructure for an enterprise. The distributed architecture of cloud data storage facilitates the customer to get benefits from the greater quality of storage and minimized the operating cost. This technology also brought numerous possible threats including data confidentiality, integrity and availability. A homomorphic based model of storage is proposed, which enable the customer and a third party auditor to perform the authentication of data stored on the cloud storage. This model performs the verification of huge file’s integrity and availability with less consumption of computation, storage and communication resources. The proposed model also supports public verifiability and dynamic data recovery
