Is there any activity to define SCHC rules for DTLS?
I want this for Unmanned Aircraft (UA) Network Remote ID (Net-RID)
communications from the UA to the Net-RID Service Provider (SP).
See
https://datatracker.ietf.org/doc/draft-moskowitz-drip-secure-nrid-c2/
I am compressing ESP traffic using rfc 8750 and:
https://datatracker.ietf.org/doc/draft-mglt-ipsecme-diet-esp/
SCHC is negotiated in IKE (and will be in HIP) and SA tables allow the
ESP receiver to recognize a SCHC compressed ESP Header and act properly.
It is not so simple with DTLS. First UDP is below DTLS, so how do you
compress it? The way I see it, SCHC would need to be assigned an IP
Protocol type so that the transport processing can start right up with
the SCHC rule for UDP and then on to DTLS and then the cipher.
Or at least how I see the challenge.
So I am looking for any extant work on SCHC for DTLS and/or interest in
this activity.
The CoAP SCHC work, rfc 8824, dodge DTLS compression. Or that is how I
read it.
Thanks
Bob
