Research Summary  

An Adaptive Trust-Aware Brokerage in Cross-cloud Federation
Cross-Cloud Federation (CCF) is beneficial for heterogeneous Cloud Service Providers (CSPs) for expanding their service footprints without any predefined and long standing agreements. This research establishes the need of trust awareness in CCF as a unique case due to the heterogeneous, multilevel and dynamic nature of federation. Existing works in trust evaluation for cloud computing proves deficient to fulfill the requirements of cloud-to-cloud trust paradigm mainly due to their user centric, non-hierarchical and non-composite nature. Novel solutions for trust and reputation evaluation in Cross-cloud federation are required such that their underlying mechanisms are aligned with the nature of federation construction.
