NIST Special Publication 800-63C-4: Federation and Assertions
Description: These guidelines provide technical requirements for federal agencies implementing digital identity services and are not intended to constrain the development or use of standards outside of this purpose. This guideline focuses on the use of federated identity and the use of assertions to implement identity federations. Federation allows a given CSP to provide authentication and (optionally) subscriber attributes to a number of separately-administered relying parties. Similarly, relying parties may use more than one CSP.
