Enhanced Framework for Authentication as a Service to Ensure Security in Public Cloud Environment

Abstract

Cloud computing is sprinkling widely the user and cloud service providers are enabled to use various resources or services inexpensively and simply without owning all the resources required. Cloud provides cost effective resource utilization and also it provides reliable and flexible usage of computing needs. IT companies are interested in migrating to cloud environment. Cloud computing provides various advantages such as lower computer costs, improved performance, data reliability, unlimited storage etc. Beyond the advantages of cloud computing, it has many issues in security, trust, scalability etc. Among these issues, security is the main issue in cloud environment. To solve this issues in cloud, this paper proposed a novel framework for Authentication as a Service (AaaS) in cloud computing. Authentication is provided as a Service to the cloud users. This paper also describes working components in the AaaS framework. It is an added advantage for Cloud Service Provider (CSP), when this framework is being adopted.
