Re: [TLS] Straw poll on TLS SRP status



Note that I am not against SRP at all. Although the EAP-SRP effort seems to have been abandoned, it still has method type number 19 in IANA.

I think SRP should not be a stand-alone extension, but rather that it should be introduced as part of EAP.

The choice is between separate extensions for SRP and for each authentication method, or to introduce them all at once under EAP, as was done in IKEv2.

I really think you should give the user the choice between IPR- laden methods (such as EAP-SRP) and IPR-free methods such as EAP-MD5.

As you indicate, your bias affects how you frame the issue and what premises you accept. In actuality, your point is ironically a good one in favor of making TLS-SRP Proposed, precisely because it's a good thing to have a choice between a strong password solution (TLS-SRP) and a weaker one (EAP-MD5?) in TLS.

And given that SRP's licensing terms have made it the most widespread
of the various strong password techniques, it's the only viable
candidate for Proposed status, if you believe that it is to the
benefit of the greater good to have a strong (against passive and
active dictionary attack), well-tested, and standardized mechanism
for password authentication over TLS.  Then let the market decide.
