Network Coding Based Cloud Storage Security for Enhancing Reliability

Cloud computing is fast growing technology which facilitates more and more users and organizations shifting towards opting their services to cloud. Cloud computing provide services like data storage, software and infrastructure. When we outsource storage as a service there is possibility of data loss. In this paper we provide a scheme which gives Reliability in terms of Fault tolerance and availability in the cloud storage. In this paper we use Regenerating codes, which are a class of codes proposed for providing reliability of data and efficient repair of failed nodes in distributed storage systems. Our approach provides two layers of security for reliable system. In first layer, check CRC [Cyclic Redundancy Check] and in second layer use Erasure Coding [Regeneration Code] for reliable storage system.
