Hi, we are students at Munich university and we trying to get GEA3 running on openbsc in nitb mode. GSM and GPRS are working, also authentication (+ GSM A5/1 encryption) and libosmo-crypt-a53 is installed, but we didn't get the plugin running (It's loaded, but we think it isn't registered). In the IRC Channel we got the information that it's actually not fully implemented and should ask here.
Has anyone got GEA3 working in openbsc with real phones?
Thanks for your time and help.
With best regards, Alexander and Stoffl
(We use the SymoSIM-GR1 SIMs and nanoBTSs 165g)

Well my patches to libosmocore implementing GEA3/GEA4 are pending in the list awaiting review for months :) I hope to finally push Holger into merging it during upcoming OsmoDevCon this week.
After that you won't need any 3rd-party libraries but I think there got to be some changes made to OpenBSC in order to support that. Most importantly - we use sqlite as HLR at the moment which makes it impossible to handle GSM and GPRS auth. requests at the same time. I think we need dedicated AuC/HLR which is fully async and can hide sqlite ugliness from the rest of the code in order to make it work.

Not yet, but I'm looking forward for your results :)

Sounds great! :) Can you provide us a link to your up to date patches, please? We only got this weak left to get the project running. I hope we can make it :)

Hm, OK. So, for testing we have to disable the GSM auth and enable the GPRS auth? Is that possible? I can't remember a option for that but I'll have a look at the config tomorrow.

I hope we get something useful ;)
