It is common practice today to use IP access control.This seems to be an easy-to-use method, but in fact there are a lot of questionable issues connected to it. A Shibboleth-based authentication and authorization infrastructure (AAI) offers a solution for these issues. For this reason the AAR project was begun in 2005 with the goal of building a Shibboleth infrastructure for both German higher education and research and for the Internet portal for scientific and scholarly information called vascoda. Within just two years, the project attracted a very high level of interest. This article describes how we built the Shibboleth infrastructure and it will show the current status of the DFN-AAI federation for German higher education and research.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
