Efficient scheduling for multi-block updates in ierasure coding based storage systems

Abstract

High-speed Internet and ubiquitous networks access become available to clients for access everywhere at any time. Cloud Storage may be a model of internet on-line storage wherever information is keep in storage that typically hosted by other parties. Data robustness is a major requirement for storage systems. A decentralised erasure code is suitable to be used in a distributed storage system. We built a cloud storage system that supports the performance of data forwarding in secure way by use an AES and Proxy re encryption. In this model owner will forward the information with AES Encryption and in cloud storage again the information will divide into several pieces in small size, for this process we will use a key dividing method. Data will place in different storage locations. If the valid user access the data cloud will retrieve the information as reversible manner.
