Re: [Emu] Review of draft-clancy-emu-eap-shared-secret-01

Michaela,

Please feel free to start the discussion on algorithm selection.  The 
DT output is just "one" opinion.  If there is an argument for or 
against the choices of algorithms, the WG I am sure would want to hear it.

I am not entirely sure CCM is the right mode, but I am open to discuss that.
