OpenStack is an open source cloud computing project that is enjoying wide. While many
cloud deployments may be stand-alone, it is clear that secure federated community clouds,
ie, inter-clouds, are needed. Hence, there must be methods for federated identity
management (FIM) that enable authentication and authorisation to be flexibly enforced
across federated environments. Since there are many different FIM protocols either in use or
in development today, this paper addresses the goal of adding protocol independent …

The security of cloud services is being jeopardised by a proliferation of weak username and
password combinations. As organisations continue to satisfy their computational
requirements with multiple cloud services, users are failing to devise numerous unique
username/password combinations. Federated identity management offers an enticing
evolution in cloud service authentication; to offer greater interconnectivity and enhanced
security. As an established Cloud operating system, OpenStack is developing federated …
