An Optimal Cooperative Provable Data Possession Scheme for Distributed Cloud Storage
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 5
Abstract
In recent years, cloud storage services has become a faster growth and makes large profits by providing the services to the customer for their needs on the internet and data sharing. Cloud environment provides the services at low cost, scalable position independent platform for the storage of client’s data. Though it provides good services, cloud environment is based on the open architecture and with interfaces. It has capabilities to incorporate with multiple internal or external services together to provide the ability to exchange data’s and use information so that we call such a distributed cloud environments as a multi- cloud or hybrid cloud. Provable data possession (PDP) is a technique for ensuring the integrity of data in cloud environment. Provable data possession is such a probabilistic proof technique for a storage provider to prove the integrity and ownership of the clients’ data without downloading data. We present an optimal cooperative PDP (CPDP) scheme based on homomorphic verifiable response and hash index hierarchy.
