Hi Mike, to some extent I think my question is not about specific
security characteristics, but rather whether its realistic for our
group to mandate that both server & native clients have the *same*
security characteristics - particularly the ability to 'securely'
authenticate to the AS on the token endpoint.
Well given the explanation Justin just gave, they do not. As I understand
your initial query, redefining a native/embedded app as "confidential"
doesn't
alter that reality. But my first question about requirements still is
relevant:
what are you trying to protect from whom, and what is the level of risk that
your profile of oauth is willing to tolerate?
Mike
thanks

Hi, the Online Media Authorization Protocol (OMAP) is a (as yet

We want to support both server & native mobile clients. It is for
the second class of clients that I'd appreciate some clarification
of 'confidentiality' as defined in OAuth 2.
OAuth 2 distinguishes confidential & public clients based on their
ability to secure the credentials they'd use to authenticate to an
AS - confidential clients can protect those credentials, public
clients can't.
Notwithstanding the above definition, the spec gives a degree of
discretion to the AS
The client type designation is based on the authorization server's
definition of secure authentication and its acceptable exposure
levels of client credentials.
Give this discretion, is it practical for the OMAP spec to stipulate
that 'All Clients (both server & native mobile), MUST be
confidential', ie let each individual OMAP AS specify its own
requirements of clients and their ability to securely authenticate?
Hi,
Can you say exactly what your security requirements are before trying
to determine which
(if either) is the right answer? I've got some concerns in this area
that I'm trying to understand
and am not sure if they're related to your concern or not. Part of
this is that I really don't
understand what the difference is between a "public" client and a
"confidential client" and
rereading the draft isn't helping me. In particular, can a iPhone app
with a UIWebView *ever*
be a "confidential" client, and if so how?
Mike
