    Semantics Of Delegation In Federated Cloud
    (Library Information Services, COMSATS University Islamabad, Lahore Campus, 2017) Numan Ahmad; FA15-RCS-005; LHR TP 6915; Dr. Adnan Ahmad
    In federated cloud different cloud service provider allow each other to use their unused resources at some cost when their own resources are not enough. Or they collaborate with each other by delegating different services which other CSP (cloud service providers) are not providing. Before delegating they need to get pre-approval from some administrative authority which is time consuming task and can create administrative bottleneck. There should be a mechanism in federated cloud that allow the user to delegate permissions without taking pre-approval i.e. Ad-hoc Delegation. In this thesis, we explored the semantic of decentralized ad-hoc delegation in federated cloud and proposed a framework that explains the essential characteristics for delegation in federated cloud. We also developed a model, based on framework, that explore the semantics of decentralized ah-hoc delegation in federated cloud. Moreover, the model is formulated through Colored Petri Net using CPN-tools to verify it’s working.
