Research of Security Strategy of Cloud Storage

Abstract

Cloud storage is a new extension and developed concept on the base of the cloud computing, aiming at providing data storage and transaction access service. On the base of the analysis of the basic concept of cloud storage, make the research and analysis on the safety of cloud storage. For the unauthorized access, data leakage, data access breakdown and other security problems, poses some security policies, including a challenge-response cloud storage identity authentication, encryption storage based on key associated with the username and a fast data recovery service which is parallel with data access. Hope cloud storage can provide a service of confidential, reliable and authentication.
