Trust-aware federated IdM in consumer cloud computing

Cloud computing paradigm has emerged as the natural evolution and integration of advances in several areas including distributed computing and consumer electronics. In this complex ecosystem, security and identity management challenges have arisen, given their dynamism and heterogeneity. As a direct consequence, dynamic federated identity management has arisen as an indispensable mechanism to enable the global scalability that is required for the successful implantation of Cloud technologies. With this requirement in mind, we present a trust-aware IdM architecture based on privacy and reputation extensions compliant with the SAMLv2 standard media.
