Enhancement in Security for Intercloud Scenario with the Help of Role-Based Access Control Model

Abstract

Cloud according to the latest buzz is the third wave of digitization. Cloud brought all things back at the center. Cloud redefines the way of computing—“where you computing is not important than how you compute”. Sharing of public resources like platform, software and infrastructure easily depending upon requirements. The connectivity of cloud eroded the division of resource sharing. The ability to access data from the cloud—anywhere, anytime—increases the security risk. Security is an essential ingredient to reduce security risk. Trust on technology is good, but as data owner is not with data all the time, so control is better. Cryptographic scheme, identity-based proxy re-encryption, is used to transform data before transferring into public environment. Data owner is not with data, so rule-based data-centric solution is proposed to keep data secure. For preventing unauthorized access of data, role-based authorization access control is developed. The solution is developed using OpenStack.
