A SECURE ERASURE CODE-BASED CLOUD STORAGE SYSTEM WITH SECURED DATA FORWARDING

High-speed networks and ubiquitous Internet access become available to users for access anywhere at anytime. Cloud computing is a concept that treats the resources on the Internet as a unified entity, a Cloud storage is a model of networked online storage where data is stored in virtualized pools of storage which are generally hosted by third parties. Hosting companies operate large data centers, The data center operators, in the background, virtualized the resources according to the requirements of the customer and expose them as storage pools, which the customers can themselves use to store files or data objects. Physically, the resource may span across multiple servers. Data robustness is a major requirement for storage systems. There have been many proposals of storing data over storage servers. One way to provide data robustness is to replicate a message such that each storage server stores a copy of the message. A decentralized erasure code is suitable for use in a distributed storage system.
