Abstract
Existing approaches for management of digital identities within e-learning ecosystems imply defining different access parameters for each service or application. However, this can reduce system security and lead to insufficient usage of the services by end-users. This chapter investigates various approaches for identity management, particulary in a cloud computing environment. Several complex issues are discussed, such as cross-domain authentication, provisioning, multi-tenancy, delegation, and security. The main goal of the research is to provide a highly effective, scalable identity management for end-users in an educational private cloud. A federated identity concept was introduced as a solution that enables organizations to implement secure identity management and to share information on the identities of users in the cloud environment. As a proof of concept, the identity management system was implemented in the e-learning system of Faculty of Organizational Sciences, University of Belgrade.
