Proof of Retrievability Using Elliptic Curve Digital Signature in Cloud Computing

Abstract

Cloud computing is a general term that includes everything which is delivered as a service. Cloud computing can be identified as a technology which leverages economic growth and improvisation of usage of resources on demand. In the dream of computing world, service providers turn their infrastructure world into an environment where organizations can do their business by running their applications over the internet. Apart from that the cloud storage services enables the end users to enjoy their facility by moving their entire data onto the cloud. This facilitates the technology to focus on various security issues and challenges that has to be resolved. This paper discusses in detail about deploying a protocol by using Elliptical Curve digital signature algorithm. This proposed protocol is established to enforce a security proof by checking for the data integrity. The protocol ensures the security against third party auditor and security against the untrusted server. This paper proves its integrity of the data through a formal analysis.
