“…3 we can also see that for making authorization decision SAML is based on XACML [16], which has not been implemented yet. We have our own XACML-compliant authorization system [1], which has been successfully deployed and extended for taking into account trust information in the access control policies. So we are going to integrate our SP with such system to grant or to deny permissions.…”

Abstract. Federation in identity management has emerged as a key concept for reducing complexity in the companies and offering an improved user experience when accessing services. In this sense, the process of trust establishment is fundamental to allow rapid and seamless interaction between different trust domains. However, the problem of establishing identity federations in dynamic and open environments that form part of Next Generation Networks (NGNs), where it is desirable to speed up the processes of service provisioning and deprovisioning, has not been fully addressed. This paper analyzes the underlying trust mechanisms of the existing frameworks for federated identity management and its suitability to be applied in the mentioned environments. This analysis is mainly focused on the Single Sign On (SSO) profile. We propose a generic extension for the SAML standard in order to facilitate the creation of federation relationships in a dynamic way between prior unknown parties. Finally, we give some details of implementation and compatibility issues.

“…When computing trustworthiness using the indirect approach, PTM assigns weights to the trust values reported by the recommenders which reflect the reliability of the sources. Almenarez et al also present TrustAC [3], which defines access control policies based on trust values obtained from PTM.…”
