Hitesh Khamesra commented on GEODE-2413:
----------------------------------------

[~bschuchardt] It's not about encrypted UDP communication. In peer-to-peer 
authentication coordinator first, authenticates the new member when it joins 
the cluster. Then coordinator sends the new view with(new-member), and then 
new-member authenticates coordinator. This way it makes sure It joined the 
right cluster. I don't see the later code in geode as we have re-implemented 
this layer.

> accepting view message

> In peer-to-peer authentication, coordinator authenticates the joining member. 
> Then coordinator includes that new member in the cluster and sends new view 
> message. This view message should include coordinator's credential so that 
> joining member can authenticate coordinator as well (i.e. mutual 
> authentication)
