That sounds OK with me.

Subject: [Openid-specs-ab] Definition of Authentication

Having seen the recent thread around client secret etc., I am confident that we have problems with the current definition of Authentication.

Currently, it is:

Process of verifying that an Entity is the owner of an Identity.

It is unclear what is "owner" etc., and is too hand-wavy. For example, what is the owner of the identity in the case of Client Authentication?

We should adopt either ISO18014 or X.1252. I feel X.1252 is slightly better.

It is:

Process used to achieve sufficient confidence in the binding
between the entity and the presented identity

I Propose to adopt this definition.
