Draft SP 800-63 Revision 1: E-Authentication Guideline is available for public comment. It supplements OMB guidance, by providing technical guidelines for the design of electronic systems for the remote authentication of citizens by government agencies. The revision represents an expansion and reorganization of the original document, broadening the discussion of technologies available to agencies, and giving a more detailed discussion of assertion technologies. Changes intended to clarify the pre-existing requirements are also included in the revision. Comments will be accepted until April 10, 2008. Comments should be forwarded via email to eauth-comments@nist.gov.
