Hi all, 

Igor raised an interesting question during the meeting in context of the security threats, namely: 

" Do we have the requirement to authenticate the originator? "

I couldn't provide him an answer during the meeting because I was not quite sure whether he was asking the question in the style of 

"Do we need end-to-end security or is a hop-by-hop security solution good enough?"

So, I am not quite sure how to interpret the question. 

Ciao
Hannes
