Taxonomy Attribute Set Based Authentication And Flexible Access Control For Cloud Storage

Cloud computing is known as “Utility”. Cloud Computing enabling users to remotely store their data in a server and provide services on-demand. Since this new computing technology requires user to entrust their valuable data to cloud providers, there have been increasing security and privacy concerns on outsourced data. We can increase security on access of the data in the cloud. However there are security concerns on outsourced data as the cloud servers are treated as untrusted. To overcome this problem many Attribute Based Encryption (ABE) techniques came into existence for secure access control. These techniques suffer from problems in implementing flexible access control mechanisms. A hierarchical attribute based solution which provides fine grained access control besides making it scalable. In this paper we implement this security scheme and build a prototype application that demonstrates the proof of concept. The empirical results revealed encouraging results.
