Hi all,

I provided the reference that I had most readily at hand, but indeed: there are 
a number of works starting with Huguenin-Dumittan that are a much better and 
tighter analysis of exactly the properties we require of TLS 1.3’s key 
exchange.  Anyway, by all of the above: KEM in TLS is very well understood by 
now.

Cheers,

Thom
