Hi there,

I would like to know how PFS is achieved for first CHILD_SA that is
created as part of piggyback in AUTH exchange.

 

RFC 4306 says no KE will be exchanged and RFC 4718 says no D-H group is
exchanged for first CHILD_SA. 

 

Does it mean the first CHILD_SA will inherit all keys from first
SA_INIT? 

 

If anybody know the answer for this, can you please tell to me?

 

Thanks in Advance,

Anil
