Oauth is primarily used as a permission proxy for an application accessing another application on behalf of a user. I think it is generally overly complex for many M2M device level scenarios.
Cuero/all,
Thanks for the information. I looked mainly at the security document for now. Having reviewed and commented other aspects earlier.
One question is, why the de facto standard OAuth 2 can't also be used for authentication here? It is a mechanism for API calls, not every call e.g. some of those infamous Twitter "bots" and similar services make are by a human actor either. And yet they
use the same auth protocols and mechanisms there.
In fact, the AirLink team and product families are mentioned together with OAuth and M2M a lot, too, so it's not like Sierra or AirLink would not use it.
Aside from that, in the documentation of the current approach, username/password is presented as the only option. At the current (transport, smart container) client we have numerous cases, where SSH keys are preferred over exchanging username/password,
even if those should be hashed or encrypted, there's always a risk of sniffing or tampering. At least the additional option of such keys should be offered.
Where devices allow, e.g. if they use a SIM card, Java Card or similar secure element, this Secure Element could also further improve security and Trust of M2M communications. When do you plan to add any of that?
Regards,
Werner

I think this would be a great idea. I have definitely interested. Do you
have a link to M3DA information?

Subject: [m2m-iwg] M3DA presentation
Hi All,
It has been discussed on this list a couple of weeks ago. We?d like to do a
quick presentation on the M3DA protocol that we are proposing in the Mihini
project context.
If you are interested we could add it to the next weekly call agenda.
This would be the occasion to cover M3DA basics, and have an open discussion
and comparison with other existing protocols, specifically the ones
available in this working group.
Regards,
Cuero

Sorry I did not mention that a presentation was attached. And more importantly here is the link to the actual specification:

Thanks for catching this.
