Hi Kevin and Paul,

I think the key-centric stuff is interesting and worthwhile, but to some 
extent it is outside the scope of CFRG.   Can I ask that the CFRG 
presentation on this topic cover the crypto mechanisms and protocols 
that are relevant for a key-centric architecture, rather than focus on 
the public-key authentication architecture itself?

Not trying to discourage work in this area, just trying to make sure 
that agenda time covers algorithms and protocols first.

David
