Re: [RFC sim-authenticate PATCH 2/3] Added doc/sim-authentication-api.txt.
Hi Marcel,
2011/1/3 Marcel Holtmann <marcel(a)holtmann.org>:
yep, that is similar to what I was thinking about.
I'll update the proposal.
Andrew is currently
looking on how to do SIM application discovery. So I like to get his
input on this as well.
The AT+CUAD looks straightforward enough. Unfortunately I've yet to
see a modem implementing AT+CUAD.
On AT command modems, we are pretty much tight into SIM application
discover and execution of authentication methods. At least when reading
the specification. I have not yet tested this since right now we are not
even bothering with SIM application details inside oFono at all.
For WISPr 2.0 and 802.1x we will need to make this work as well.

Is there a public specification for GBA by any chance?
33.220 is specifies the algorithm and 24.109 contains the protocol.
I'd recommend starting from the examples in 24.109, they are most
easiest to digest.
