RE: Symptoms vs. Causes

I agree with Eliot and based upon what we know about phishing and UI, the more mandatory and automatic and easy to use you make the mutual authentication, and the less you leave to the user the better off you are.

Quite so.

It's about both.  We can severely limit phishing through the use of mutual authentication.  The UI part is that whatever mutual authentication you use has to be both mandatory AND easy to use.  The IETF has a responsibility in as much as we need to provide the protocol infrastructure that allows the UIs to be correct.  IMHO it's not just our responsibility - W3C has a role to play, and so do the IEEE and the ITU in as much as today's smart cards aren't really that smart.
