Federation offers an affordable opportunity for small and medium cloud providers to become as competitive as the biggest counterparts. However, in order to establish a federated cloud ecosystem, it is needed to rely on an efficient security infrastructure enabling authentication among clouds. Assuming a scalable federated cloud environment, the management of security can become very hard due to the number of authentications and trusted relationships that have to be established. Nowadays, the latest trend in authentication is the Identity Provider/Service Provider model. This paper aims to investigate a distributed IdP/SP infrastructure based on the concept of delegated authentications, evaluating its possible utilization in a federated cloud scenario.
