Secure Service Provisioning in Cloud using Attribute Based Encryption

Abstract

Today, cloud computing has become important research area and more enterprises are adopting the Cloud based strategy for their businesses. In this case, user access control is the primary concern for cloud users and cloud service providers. User accesses are key factor in determining how much they have to pay to the service provider (SP). So, SP needs to deploy secure access control mechanism in provisioning the services to the users. In cloud computing, services are delivered as web services using SOAP message format. And to protect service provisioning to unauthorized users, many security access control mechanisms have been proposed. This paper intends to examine how Attribute Based Encryption mechanism used to control users’ accesses among cluster based private cloud and data center private cloud in our university campus. By using this mechanism, service providers can ensure that secure services are delivered only to the authorized users.
