Abstract

"Current market trends need solutions/products to be developed at high speed. To meet those requirements sometimes it requires collaboration between the organizations. Modern workforce is increasingly distributed, mobile and virtual which will incur hurdles for communication and effective collaboration within organizations. One of the greatest benefits of cloud computing has to do with improvements to organizations communication and collaboration, both internally and externally. Because of the efficient services that are being offered by the cloud service providers today, many business organizations started taking advantage of cloud services. Specifically, Cloud computing enables a new form of service in that a service can be realized by components provided by different enterprises or entities in a collaborative manner. Participating parties are usually loosely connected and they are responsible for managing and protecting resources/data entrusted to them. Such scenario demands advanced and innovative mechanisms for better security and privacy protection of data shared among multiple participating parties.

In this thesis, we propose an access control delegation approach that achieves federated security services and preserves autonomy and privacy sharing preferences of involved parties. An important feature of our mechanism is that each party will not need to reveal its own sensitive information when making a global decision with other collaborators, which will encourage a wide range of collaboration and create more business opportunities."--Abstract, page iii.
