[00:00:17] <John Border_web_419> I don't think it is appropriate for this discussion.  More when we get to the details of the document.
[00:00:21] <Antoine Fressancourt_web_568> @John, I think Detnet guys have such concepts in the expression of their routing constraints

[00:18:22] <Spencer Dawkins_web_624> I'm putting details in the CoviMD document, but since someone asked -  PILC produced [RFC 3819 - Advice for Internet Subnetwork Designers](https://https://datatracker.ietf.org/doc/rfc3819/)

[00:22:10] <Jamey Sharp_web_488> so many questions about drkey but definitely no time to ask them here :sweat_smile:
[00:22:13] Dan Voyer_web_604 joins the room
[00:22:18] <Antoine Fressancourt_web_568> Can DRKey be used in a non-interactive context ?
[00:22:47] <Juan de los Galanes_web_429> For e.g. batch processing?
[00:23:25] <Antoine Fressancourt_web_568> Or use it in a similar context as NIKE
[00:23:59] Ali Hussain_web_717 leaves the room
[00:24:05] Ali Hussain_web_943 joins the room
[00:24:09] <Juan de los Galanes_web_429> sorry, I don't know how NIKE works :(
[00:25:56] <Antoine Fressancourt_web_568> In NIKE, you use a remote party's public key to compute a shared key that you can use to secure later messages, and this remote party uses your own public key to compute the same shared key
[00:26:11] <Antoine Fressancourt_web_568> (Very schematically)
[00:26:37] Vidhi Goel_web_670 joins the room
[00:27:16] <Juan de los Galanes_web_429> Thanks for the explanation!! I also just read an abstract about NIKE. With DRKey we need to share the e.g. L1 keys somehow. It can be done upfront (every Monday at 8am) and then use them in the data plane, but that has the problem that there is no key revocation in DRKey (by design)
[00:28:15] <Juan de los Galanes_web_429> For DRKey the exchange is done using asym crypto, but the key derivation itself is based on AES, which is fast enough to be done in some nanosecs
[00:29:00] <Juan de los Galanes_web_429> The whole idea of DRKey is to derive the key _every time_ we see a new packet, instead of keeping state about the sources.
[00:29:10] <Antoine Fressancourt_web_568> ok
[00:29:33] <Antoine Fressancourt_web_568> Thanks for this information, I will look deeper at DRKey
