wanting to ensure that the nodes can't use the amount of hmacs applied to determine the position in the route, tho has been a while since I've swapped that stuff in to actually think about it 20:24 < roasbeef> I think the n^2 thing is an attempt to hide the path length information (haven't read the latest post yet, so I'm prob working off a dated mental model) 20:26 < BlueMatt[m]> Right, it wasn’t clear to me why you need n^2 for that. It seemed like you should be able to just have a big enough packet and push hmacs to the front and shift 20:42 -!- noxim [~AdminUser@user/noxim] has quit [Ping timeout: 272 seconds] 20:49 -!- joostjgr [~joostjgr@81-207-149-246.fixed.kpn.net] has quit [Remote host closed the connection] 20:49 -!- joostjgr [~joostjgr@81-207-149-246.fixed.kpn.net] has joined #lightning-dev 20:51 -!- Aaronvan_ [~AaronvanW@user/AaronvanW] has quit [Read error: Connection reset by peer] 21:04 -!- jon_atack [~jonatack@user/jonatack] has joined #lightning-dev 21:05 -!- jonatack [~jonatack@user/jonatack] has quit [Ping timeout: 272 seconds] 21:14 -!- rusty [~rusty@115-64-38-152.static.tpgi.com.au] has quit [Ping timeout: 246 seconds] 21:23 -!- AaronvanW [~AaronvanW@user/AaronvanW] has joined #lightning-dev 21:26 -!- noxim [~AdminUser@43.224.169.86] has joined #lightning-dev 21:26 -!- noxim [~AdminUser@43.224.169.86] has quit [Changing host] 21:26 -!- noxim [~AdminUser@user/noxim] has joined #lightning-dev 21:30 -!- noxim [~AdminUser@user/noxim] has quit [Ping timeout: 248 seconds] 21:56 -!- AaronvanW [~AaronvanW@user/AaronvanW] has quit [Ping timeout: 272 seconds] 23:01 -!- test_ [flooded@gateway/vpn/protonvpn/flood/x-43489060] has joined #lightning-dev 23:03 -!- _flood [flooded@gateway/vpn/protonvpn/flood/x-43489060] has quit [Read error: Connection reset by peer] 23:38 -!- noxim [~AdminUser@user/noxim] has joined #lightning-dev 23:55 < joostjgr> BlueMatt: If you naively push hmacs to the front and shift, it becomes possible for nodes to shift blame onto upstream nodes. They can mess with data in the block that is later included in upstream nodes' hmacs and then shifted out. 23:55 -!- AaronvanW [~AaronvanW@user/AaronvanW] has joined #lightning-dev 23:56 < joostjgr> Sender doesn't know what the messed up, shifted out data was, so they can't verify that the upstream node's hmacs were correct given the data they received --- Log closed Fri Nov 04 00:00:07 2022
