Scalability of trust and metadata exchange across federations

In eResearch federated identity and access management allows researchers to share their valuable resources with fellow researchers in other institutions in the same federation or even across federations. The latter aspect requires trust establishment between federations. In eduGAIN such trust establishment is realised through trustful metadata exchange between federations. This contribution proposes a new solution that is more scalable and brings the current eduGAIN solution one step towards a fully distributed architecture.
