True, I think! Is there a practical application for this?
( I can think of one trivial example: "a message system is
psuedonymous, but I want to send an anonymous message!" )
I'm asking myself whether "anonymous DH" is confusingly named.
Perhaps it should be called psuedonymous DH because it creates
psuedonyms for the life of the session? Or, we need a name
that describes the creation of psuedonyms, de novo, from
an anonymous starting position?
