Dear authors,

After implementing the changes with respect to the former draft with
exclusion of the pairwise mode, I have a question.

Why do I need in the exteranal_aad and in the context both
counter signature parameters and counter signature key parameters. One
looks sufficient to me.

Secondly, It is not clear to me how pairwise keys solve the problem of a
blocked group communication. 
When using block in the multicast request, I assume that using unicasts
to as many destinations is more straightforward.

Greetings,

peter
