Re: [dtn-security] Authentication and Authorization in DTN

Well, I'd love to see someone try to tackle key mgmt anyway
(there's an expired I-D with some requirements there).

As Keith also said fragmentation mixed with security is also
crying out for some better solution.

There's also some (possibly easier) work that could be done
on authorization, e.g. looking at how one might do something
analagous to RADIUS in DTNs. (In particular, answering the
question: "why should I take your bundles into custody?")
