Do you have a suggestion for improved language. >From your response & Joel's, I see bullet #2 is the only one that calls out the need for mutual authentication and it just states that with no additional details. That is fine, but the subject for section 3.1 should be something more like authentication and identifiers to represent the content better. > >> Are all mutual auth schemes in scope?

Is there a reason we should > restrict the mutual authentication schemes to a subset. You don't have to, but the header of the section makes me think this is going to happen in the section. Maybe setting a baseline would be good if possible. Not using passwords - so a secure form of mutual authentication would be good if the requirements are only high level. > > ---- >>I share the same concern as others for secure transport, but since there are >>already discusses on that, I have one comment to add to the existing >>discusses below. > > You have a concern regarding the secure transport? KM: Yes, the wording that allows for insecure transport. Same concern expressed by other ADs. My understanding is that other people had a concern regarding the insecure transport. I have provide an example of the BGP data feed utilized by http://www.routeviews.org/ project.

I'll have to look through Alissa's discuss, but isn't integrity a concern if confidentiality and privacy are not? I'm sure once this type of text is altered and used to make important decisions, this will come back to bite us. > > ---- >>Section 3.4: In the following text: >> SEC-REQ-15: The integrity that the message data is not repeated means >> that I2RS client to I2RS agent transport SHOULD protect against >> replay attack > >>I'm not sure why this just doesn't say: >> SEC-REQ-15: I2RS client to I2RS agent transport SHOULD protect against > > replay attack >>The additional text doesn't add anything and sounds a bit confusing. > > Sue: Is this ok.
