Trust based Federated Cloud Identity Management System

Sharing and storage of sensitive identity information at third party provided storages raise issues like lack of trusted security and privacy mechanisms, therefore requires some security and trust establishment technique. Further, identity management system based on federated architecture to provide security against various attacks seems to be a worthwhile solution, since in case of any security breach such as theft of identity; loss impact will be minimal. However, with the distribution of identity information at multiple locations numerous other concerns such as lack of trust, transparency, security and delay in response due to heavy processing among many others arise that eventually limits their adoption and affect their credibility also. Therefore, design and integration of trust establishment module in the federated Cloud identity management system is a significant research direction that should be explored in detail.This thesis will focus on research in federated Cloud identity management domain to design and implement trust based efficient yet secure identity management solution for Cloud environments.
