PROJECT TITLE :

Efficient Identity-based Provable Multi-Copy Data Possession in Multi-Cloud Storage

ABSTRACT:

A significant number of clients currently store multiple copies of their data on a variety of cloud servers. This helps to improve the data's availability as well as its long-term stability. The presentation of some provable data possession (PDP) protocols for multi-copy is made with the intention of ensuring the consistency of multiple copies. On the other hand, the vast majority of earlier PDP protocols consider all copies to be stored on just a single cloud storage server. When faced with such a situation, using multiple copies of something makes little to no sense. In addition, numerous PDP protocols are reliant on a method known as public key infrastructure (PKI), which is plagued by a wide variety of security flaws and carries with it a significant increase in the amount of money spent on Communication and computation. We offer an innovative identity-based PDP scheme of multi-copy on multiple cloud storage servers in order to improve both the safety and the effectiveness of the system. According to our plan, all of the copies are sent to various servers that are part of the cloud storage service, and these servers collaborate to store the customer's data. Through the use of homomorphic verifiable tags, it is possible to check the integrity of each and every copy at the same time. In the paper, both the system model and the security model of our scheme are described in detail. Our plan's safety can be demonstrated thanks to the computation Diffie-Hellman (CDH) hard problem, which was solved by our team. The results of our analysis and evaluation experiments indicate that our scheme is both effective and applicable. The method that has been proposed is the first identity-based PDP method that can be used for multiple copies and multiple cloud servers.
