I want to know the difference between FIPS 196 (public key for authentication) and SSL for authentication. If we claim FIPS 196, which is the core of most authentication protocols in use (e.g. SSL) is it ok?

And if we use SSL for authentication between client and server can we claim implementation FIPS 196?

  • FIPS 196 has been obsoleted. Why would you want to use it?

FIPS 196 introduces two-step authentication based on Digital Signatures.

Authentication using SSL uses FIPS 140-2.
