Issue here is that guarantees (and what you want as a guarantee may not be what somebody else wants) can vary depending on scenario and deployment.

Start with a model of the protocol and the guarantees you want, then explain how to use security mechanisms to achieve those guarantees. I promised Hannes today to do a review of the current document (which I admit I haven't read) and start on some security considerations from that perspective. So expect that in the next few weeks. --Richard On 11/9/10 4:07 PM, tors...@lodderstedt.net wrote: > We think the security considerations should be based on a threat model of > OAuth.
