DFN-Verein operates an authentication and authorization infrastructure (AAI). The DFN-AAI enables users from German research and science institutions (participants) to access protected resources of providers via the research and education network, e.g., scientific publications, licensed software, supercomputers or Grid resources.
To access protected resources, users of DFN-AAI have to be authenticated by their home institution as the first step. After the successful authentication, the home institution transfers the attributes necessary for authorization to the accessed resource. In the third step, the user gains access after he is successfully authorized on the resource.
