Yes, I could believe that payload encryption was an initial design  
model, and a very reasonable one.  That's equivalent to what we can do  
today via IPsec transport mode.

Or, my recollection of those BCR design details could be wrong :-)!

I don't know if BBN has any of the BCR reports from that time frame. I  
can ask our librarian.
