CERNET Federation

Overview
The CERNET Federation is based on the Shibboleth Project of Internet2. To facilitate resource sharing among different institutions, in the institution where a user belongs, an Identity Provider (IdP) is deployed to authenticate the user and provide user information upon requests. In the institution which provides shared resources, a Service Provider (SP) should be deployed to enforce access control to those resources. For the convenience of cross-domain resource sharing, a portal for cross-domain resource sharing has been set up. A user is able to access shared resources after logging in to the portal with the username and password of his own institution.
