Survey on Improved Security in Public Cloud

Abstract

Cloud computing is computing paradigm, large number of systems are connected in private or public networks for provide data storage and also file storage because cloud has unlimited storage capacity. Security is protect the data from the unauthorized user access of data. In public cloud security will be implemented by role based encryption, attribute based encryption. All these techniques are related to encryption method. Every data can be encrypted then stored into public cloud so every data has separate encryption key for user identification because more number of users are supported by role based access control. Generally access control consist of authentication, authorization, access approval and also audit. All users assigned by specific roles.

Keywords: Cloud computing, Role Based Access Control, elliptic curves, data storage.
