16:00:31 <Shelikhoo[mds]> here is our meeting pad: https://pad.riseup.net/p/r.9574e996bb9c0266213d38b91b56c469

16:00:32 <Shelikhoo[mds]> hi~
16:00:36 <meskio[mds]> hello
16:00:47 <onyinyang[mds]> hihi o/
16:02:06 <Shelikhoo[mds]> please go ahead to add discussion topics to the pad
16:03:51 <meskio[mds]> maybe we have a quiet meeting today
16:04:13 <Shelikhoo[mds]> yeah, in theory we could pick a reading group if there is no other topics
16:04:26 <Shelikhoo[mds]> but cohosh is not here...
16:05:03 <Shelikhoo[mds]> so maybe as we all busy working on our assignment on signaling channel, there isn't a lot to discuss if everything is proceeding as planned
16:05:47 <Shelikhoo[mds]> but I will wait 2 more minutes for anyway last minute topics or anything we wants to discuss in this meeting.
16:05:49 <dcf1> there's a pets paper that might be good for reading group
16:06:02 <meskio[mds]> which one?
16:06:30 <dcf1> "Evaluating connection migration based QUIC censorship circumvention"
16:06:53 <meskio[mds]> just saw it in censorbib
16:06:53 <meskio[mds]> https://petsymposium.org/popets/2026/popets-2026-0014.pdf
16:07:38 <meskio[mds]> we could pick it up for June 11th (I'll be AFK June 4)
16:07:41 <dcf1> that's the one
16:07:54 <dcf1> Seungju Lee was at the last online FOCI
16:08:22 <Shelikhoo[mds]> I thin this paper looks nice
16:08:30 <Shelikhoo[mds]> I think this paper looks nice
16:08:45 <dcf1> I haven't read it, but my impression is that it's about tunneling just the handshake (incl. SNI) over a separate channel, then gluing it to a standard QUIC UDP connection for the remainder, using connecting migration
16:09:37 <meskio[mds]> interesting idea
16:10:47 <Shelikhoo[mds]> yeah, this is very impressive as this can be done in user mode without special privilege
16:11:18 <Shelikhoo[mds]> if we wants to do similar thing to a tcp based tls connection, then it would require raw socket
16:11:37 <dcf1> or turbo tunnel, at the cost of additional overhead
16:11:41 <Shelikhoo[mds]> which won't work on restricted device like locked smartphone
16:12:17 <dcf1> there is another little-known paper I read recently, called DNS-Morph, that does something similar, but specialized to the handshakes of obfs4 and scramblesuit
16:12:29 <dcf1> I'm going to post a summary of DNS-Morph to net4people pretty soon
16:12:38 <Shelikhoo[mds]> dcf1: you are right. I think it is more important to use this to run domain fronting on host that don't allow it
16:13:00 <Shelikhoo[mds]> so if a cdn does not allow domain fronting, but allows quic
16:13:21 <Shelikhoo[mds]> this can be used to create a data channel over a signaling channel
16:13:39 <Shelikhoo[mds]> this can be used to create a data channel using a signaling channel
16:13:51 <Shelikhoo[mds]> and a quic allowed domain fronting target
16:14:50 <Shelikhoo[mds]> but I think we can save more discussion to the reading group once we have read the paper. EOF
16:15:33 <meskio[mds]> yeah, let's discuss it then
16:15:42 <meskio[mds]> are we happy with the proposed date?
16:16:21 <Shelikhoo[mds]> it should work for me
16:16:46 <Shelikhoo[mds]> we can maybe confirm the day again next week
16:16:51 <Shelikhoo[mds]> as cohosh isn't here
16:16:57 <meskio[mds]> sure, lets check with her
16:17:35 <onyinyang[mds]> oh yeah, the 11th should be fine for me too
16:17:37 <Shelikhoo[mds]> yes. let me know if there is any more topic we wants to discuss today
16:18:30 <meskio[mds]> nothing from me
16:18:45 <Shelikhoo[mds]> Thanks everyone! have a nice rest of the day and weekend! Let's call it a meeting.
