NIST releases Electronic Authentication Guideline

Now this was an interesting find.

NIST has released a set of recommendations in Special Publication 800-63 providing technical guidance to Federal agencies implementing electronic authentication. The recommendation covers remote authentication of users over open networks. It defines technical requirements for each of four levels of assurance in the areas of identity proofing, registration, tokens, authentication protocols and related assertions.

I really liked how they detailed it here. Worth the read.
