RE: Basic Authentication - what do we have?

You wouldn't put in the password until you validated the site

How would it be available to me as SCI when I put in the password?

SBM has the site provide a signed digital hash of the url, IP address - that
will certainly nail the identity of the site you are asking for

I'm getting the feeling I didn't make the issue I was grappling with clear.
It's the Identity issue, not the Protocol Protection issue. 

I'm in a modal dialog asking me for a password. How do I know the identity
of the site asking me? Particularly when the bits of the URL I care about
are truncated off the right hand side of the title bar? (though I don't
think a typical user should be expected to parse URLs for identity
information).

Where in our proposals do we address that?

When used in conjunction with HTTPs, basic authentication is fine and
accepted. May even get medium robustness certification in the DoD when
used with FIPS 140-2 compliant TLS cipher, but I would have to check
that.

NTLM, has known issues, didn't think it was used beyond Microsoft
platforms. Digests never really took hold and both were superseded by
Kerberos V5.

I would not consider BASIC, DIGEST, NTLM as anywhere near secure.
