Re: [Dtls-iot] Fwd: I-D Action: draft-mglt-dice-ipsec-for-application-payload-00.txt

Thanks Carsten and Daniel for the quick draft. Indeed IPsec could have been a candidate if we did not have the initial goal of reusing as much of DTLS codebase  for the various IoT security operations.

Just a quick question, since you are using AES-CCM, how do you ensure different nonces for the different senders in your scheme?

To stir the pot a little bit on draft-keoh-dice-multicast-security, Daniel and I have written a short straw man draft to show how the same objective can already be achieved using existing widely deployed standards-track protocols.  This is a little less efficient, but does the job.  (Further efficiencies could be achieved by compressing away some of the redundant information, see the draft for some ideas.)

Thanks to Daniel for being available on short notice for this little mischievous act.

I’m no longer sure I don’t actually want to use this.

Grüße, Carsten
