Thank you for the work put into this document.

I hope that this helps to improve the document,

-- Section 2.3 --
About
  "a waypoint node, representing a
   gateway to an insecure portion of the DTN, may receive the bundle and
   choose to apply a confidentiality service"
how could the bundle destination could recover the plain text if there is no
security association with the encrypting waypoint? Or is it simple hop-by-hop
encryption ?

-- Section 3.2 --
Why not supporting multiple integrity-checks/signatures? After all, this would
allow the support of more than 1 integrity check / signature algorithm?
(Obvioulsy, this cannot be done for confidentility -- except if transmitting
multiple copies). There are some text related to this in section 3.7.

-- Section 8.2.4 --
More details about anti-replay of a DTN message would be welcome. E.g., is the
bundle age field used ?

-- Section 9.2 --
This section is a list of issues with BPsec but are there other WG items
attempting to solve those issues ? draft-ietf-dtn-bpsec-interop-sc does not
seem to cover those issues.
