An Efficient PDP Scheme for Distributed Cloud Storage
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 4
Abstract
Cloud computing is the use of Internet for the tasks performed on the local computer, with the hardware and software demands maintained elsewhere. It represents a different way to architect and remotely manage various computing resources. Cloud is widely used everywhere owing to its convenience, be it in simple data analytic program or composite web or mobile applications. Cloud computing is being driven by many which includes Amazon, Google and Yahoo as well as traditional vendors including IBM, Microsoft and Intel. The data should be available in the cloud for it to be accessed by many users. There are four main types of cloud storage- Multi Cloud Storage or distributed cloud storage, Public Cloud Storage, Private Cloud Storage, Mobile Cloud Storage. Distributed cloud is a combination of public and private cloud storage where some critical data resides in the enterprise's private cloud while other data is stored and accessible from a public cloud storage provider. Provable data possession (PDP) is a technique for ensuring the integrity of data stored in storage outsourcing. In this paper, we propose a method called cooperative PDP (CPDP) scheme based on homomorphic verifiable response and hash index hierarchy.
