This makes sense to me.

All,
My opinion is that BPSec should be required in the sense of: When bundle-level security is needed, you must use BPSec instead of some other mechanism with the same or similar scope.
This is the same type of qualified requirement used for TLS in TCPCLv4.
This requirement steers implementations away from private encodings/behaviors, which is desirable as Rick mentioned in the Monday meeting.

Subject: [dtn] BPbis - BPSec requirement


All,



At IETF-108 there was discussion on whether BPbis should require BPSec, and the chairs are interested in discovering the WG consensus on this matter.



Please use this thread for your comments.



Cheers,



Rick & Marc
