[13:01:41] cw-ietf joins the room
[13:01:51] Derek Atkins joins the room
[13:01:57] <derek> Shouldn't the topic be IETF-95?
[13:02:12] <kadukoafs@gmail.com/barnowlE454F816> Who would want to keep up with the times...
[13:02:30] Chris Inacio joins the room

[13:03:14] Yoav Nir joins the room
[13:03:52] richsalz joins the room
[13:04:20] kivinen joins the room
[13:04:20] Steve Olshansky joins the room
[13:04:27] <derek> Yes, we can hear you, see you, and see the slides.
[13:04:40] Philip Homburg joins the room
[13:04:45] Scott Fluhrer joins the room
[13:05:21] <Yoav Nir> I am the jabber scribe . If you want something channeled to the room mic, prefix with "mic:"
[13:05:34] Chris Inacio leaves the room: Disconnected: Replaced by new connection
[13:05:37] Chris Inacio joins the room
[13:09:16] Satoru Kanno joins the room
[13:11:49] Stefan-Lukas Gazdag leaves the room
[13:12:05] Stefan-Lukas Gazdag joins the room
[13:12:36] Satoru Kanno leaves the room
[13:16:36] Deb Cooley joins the room
[13:22:42] Dmitry Khovratovich joins the room
[13:24:05] <derek> mic: you can probably coordinate with the sec-dir chair (currently Tero, I believe) for samples of the sec-dir process + template format.
[13:24:12] vojislav vucetic joins the room
[13:24:14] <derek> s/chair/secretary
[13:24:39] sftcd joins the room
[13:24:46] Karen O'Donoghue joins the room
[13:24:50] <Derek Atkins> and yes, that was me.
[13:29:16] Dmitry Khovratovich leaves the room
[13:29:45] Dmitry Khovratovich joins the room
[13:29:52] <Yoav Nir> Do the remote participants manage to understand the audio?  
[13:30:47] <cw-ietf> yes
[13:31:09] <sftcd> in-room audio is clipping but possible to understand
[13:31:20] <sftcd> or maybe I'm hungover:-)
[13:31:32] <kadukoafs@gmail.com/barnowlE454F816> "maybe", sure.
[13:31:42] <Yoav Nir> No, it's definitely clipping
[13:32:07] <kadukoafs@gmail.com/barnowlE454F816> I don't think it's clipping in the local setup; it sounds more like
packet loss to me.
[13:32:46] <derek> It sounds like a lot of echo, too
[13:33:14] Karen O'Donoghue_5079 joins the room
[13:33:58] <Yoav Nir> I also note in the picture that the mic-on-a-stick is pointed straight up, which suggests that he's either amplifying a lot or using the computer mic
[13:35:24] <Andreas Huelsing> Yes, my laptop does not have a mic input...
[13:35:26] <Andreas Huelsing> sorry
[13:35:44] <Yoav Nir> Next Dave McGrew presenting on "State Management in Hash-Based Signatures"
[13:36:12] <Yoav Nir> https://www.ietf.org/proceedings/95/slides/slides-95-cfrg-1.pdf
[13:36:12] <Tony Hansen> @meetecho, my video of the room disappeared
[13:36:56] <Yoav Nir> slide #2
[13:37:14] <Meetecho> Tony Hansen: feed should still be up and running
[13:37:33] <Meetecho> if you're still getting slides, though, I wouldn't go with the rejoin, especially if you're interested in the conversation
[13:37:46] <Meetecho> (ansewering on your related post on vmeet as I type BTW)
[13:38:06] <Yoav Nir> slide #3
[13:38:21] <Tony Hansen> full screen refresh brought it back -- would be nice to have buttons to refresh just video stream, or just slides, etc
[13:38:33] <Meetecho> yep, on todo list already :)
[13:39:36] Tony Hansen leaves the room
[13:39:54] <Yoav Nir> slide #4
[13:40:30] Tony Hansen joins the room
[13:44:48] richsalz leaves the room
[13:44:57] richsalz joins the room
[13:49:32] Gregory Stein leaves the room
[13:50:36] <Yoav Nir> Next: Dmitry on https://www.ietf.org/proceedings/95/slides/slides-95-cfrg-2.pdf
[13:50:52] jimsch joins the room
[13:51:42] <kadukoafs@gmail.com/barnowlE454F816> meetecho: our video and audio are out of synch; it might be less
distracting if the presenter was not full-screen video
[13:52:02] <Meetecho> you mean in the room?
[13:52:15] <kadukoafs@gmail.com/barnowlE454F816> yes
[13:52:23] <Meetecho> better now?
[13:52:43] <metricamerica> yes
[13:53:15] <kadukoafs@gmail.com/barnowlE454F816> thanks!
[13:55:02] Gregory Stein joins the room
[13:57:13] sftcd joins the room
[13:59:15] <sftcd> variants of crypto algorithms - just what we want more of :-(
[14:00:50] <Yoav Nir> Different salt sizes?  Why?  Why do we need a knob there?
[14:01:37] <Yoav Nir> I mean, I realize why Password can be arbitrary length, but what are the pros and cons of choosing different sizes for the other parameters?
[14:01:54] <kadukoafs@gmail.com/barnowlE454F816> Are you planning to say that at the mic?
[14:02:11] <Yoav Nir> I haven't read the draft, so no.
[14:07:25] <derek> yikes.  Dave is clipping
[14:07:31] <derek> Ahh, much better by the end of his question...
[14:08:24] Stefan-Lukas Gazdag leaves the room

[14:15:22] Dmitry Khovratovich leaves the room
[14:15:23] Ned Freed joins the room
[14:19:53] Karen O'Donoghue leaves the room
[14:19:56] <Derek Atkins> mic: there are definitely devices that want firmware updates where the hardware will last 10-15 years.
[14:20:37] <Andreas Huelsing> mic: think of satelites
[14:21:12] Karen O'Donoghue_5079 leaves the room
[14:21:14] <Andreas Huelsing> you cannot just drop by and replace the hardware
[14:21:51] Steve Olshansky leaves the room
[14:21:52] <richsalz> i will say those in reverse order
[14:22:11] <Derek Atkins> mic: there are techniques to perform firmware updates where the update is verifyable and can be rolled-back if the update "fails"
[14:25:27] <Andreas Huelsing> mic: Just because we are unable to solve all issues with a secure signature scheme, it does not mean that we shouldn't use it
[14:25:44] Karen O'Donoghue joins the room
[14:26:55] Karen O'Donoghue leaves the room
[14:27:53] <richsalz> sorry Andreas, want me to repeat your last comment?
[14:28:08] <Andreas Huelsing> I think discussion moved on... so no
[14:28:18] <richsalz> ok.  again, sorry.
[14:28:32] <Andreas Huelsing> no problem

[14:51:19] kivinen leaves the room
[14:52:28] <Derek Atkins> mic: there are also some braid-based algorithms coming down the pipe
[14:53:36] Yoav Nir joins the room
[14:53:48] sftcd joins the room
[14:54:54] <Scott Fluhrer> What based???
[14:55:04] <Andreas Huelsing> mic: Many PQC algorithms allow for different trade-offs. CFRG / IETF could collect performance requirements
[14:55:04] <kadukoafs@gmail.com/barnowlE454F816> braid group theory
[14:55:37] <Andreas Huelsing> Is there any unbroken braid-based scheme today?
[14:56:04] <Derek Atkins> Andreas: yes, coming down the pipe.
[14:57:55] <Tony Hansen> thought for the day that I just saw that is possibly applicable here: "To improve is to change, so to be perfect is to have changed often." Winston Churchill
