Identity federations enable users, service providers and identity providers from different organizations to exchange authentication and authorization information in a secure way. In this paper we present a novel identity federation architecture for cloud services based on the integration of a cloud identity management service with an Authentication, Authorization and Accounting (AAA) infrastructure. Specifically we analyse how this type of AAA-based federation can be smoothly integrated into OpenStack, the leading open source cloud software solution, using the IETF Application Bridging for Federated Access Beyond web (ABFAB) specification for authentication and authorization. We provide details of the implementation undertaken in GÉANT s CLASSe project, and show its validation in a real testbed.

SUMMARY This paper describes the IKEv2 protocol and presents how an open-source IKEv2 implementation, in particular OpenIKEv2 has been designed and implemented. All the issues found during this process and how they were solved are also described. Finally, a comparison between existing open-source implementations is presented .

Finally, it is analyzed how the inclusion of IdM in business organizations can provide economical benefits. These benefits range from a reduction in resource requirements to the increment of potential clients thanks to the incorporation of the organization in an identity federation. Special attention is placed on the case where the telecommunications operator is established as the main point of identity providing, as a straightforward result of its already established trust relationships with a wide range of parties (clients and service providers).
