Re: [Doubango] IMS AKA authentication (ISIM or USIM based)

[Mamadou]

Yes it's supported and implementation follow 3GPP TS 35.205/6/7/8/9 and RFC 3310. It's not mandatory for IMS AKA "to be either ISIM or USIM based" at all.

Hello,

I am trying to use IMSDroid on real VoLTE deployment. 

One of the functionalities listed as supported is IMS AKA, which is mandated to be either ISIM or USIM based.

I just cannot find how this is configured in the IMSDroid client (I have version 2.548.870). The app seems to require that private and public identities, and PCSCF address be configured manually, instead of reading it from ISIM.

Is IMS-AKA really supported?, if so, how can I configure it for IMS-AKA with ISIM?

Thanks,

Juan

Doubango: sorry, I sent a private mail by mistake. I assume that this info is very useful to anyone else trying real VoLTE (compliant with GSMA IR92).

But is IMS AKA for ISIM/USIM supported in Doubango?

[Mamadou]

No, it's up to the underlying app to read the IMPI and IMPU.

[Conan Kudo (ニール・ゴンパ)]

And IMSDroid doesn't implement this, right?

[Mamadou]

Implement what?
If it's about reading the IMPI then yes or at least not open source.

[Juan Noguera]

35 series only specifies the algorithms. TS 33.102 and related specs define the security architecture. Section 5.2.2 of the Voice over IMS profile from One Voice (which is based on GSMA IR92) stands by this architecture.

In practice, AKA without ISIM and / or USIM support is not very practical. In my case, I know the information stored in some of the EFs in the ISIM (PUI, PVI and PCSCF address), but definitely not the keys and actual algorihtm.

In any case, great work!. I would be interested to know if there you have implemented ISIM support for IMSDroid, even if it requires commercial license.

Thanks,

Juan
