speaking as regular ol' member I'm not really sure what you are talking about here. You speak of bgpsec and signing - that is not origin validation, that is path validation. Origin validation is strictly and only judging whether the origin has the authority to originate announcements of the prefix. Origin validation does not ensure that the authorized AS is actually making the announcement. It is bgpsec path validation that ensures that the announcement is currently and authentically being announced by the AS. That's the "signed injection" you mention. --Sandy ________________________________ From: Brian Dickson [brian.peter.dickson@gmail.com] Sent: Friday, March 30, 2012 8:55 AM To: Murphy, Sandra Cc: Christopher Morrow; Sriram, Kotikalapudi; Chris Morrow; sidr@ietf.org list Subject: Re: [sidr] I-D Action: draft-ietf-sidr-usecases-03.txt Sandy, The use case example I included, is an origin validation use case. The problem is the inability to have "origination" (signed injection into BGPSEC) done by proxy, at all or especially by more than one party. The particular situation leading to the need for this, would be a stub AS whose router vendor does not support BGPSEC, or whose router hardware or code base is not included in BGPSEC support by their router vendor. (Doing a forklift upgrade to do BGPSEC is generally seen as #FAIL by operators.) This is likely to be a fairly common situation _among stub AS_ and, given the current requirement for origin injection for BGPSEC, addressing this _may_ impact the use cases document, for _origin validation_. I'm just saying... Brian On Fri, Mar 30, 2012 at 4:21 AM, Murphy, Sandra <Sandra.Murphy@sparta.com<mailto:Sandra.Murphy@sparta.com>> wrote: Brian, Chris. The usecases draft was intended to describe origin validation use cases. Route leaks (and other path validation issues) might need their own usecases draft.

I'm not against this, though we've got a document hanging out post WGLC (perhaps it ought to be re-reviewed if the changes were significant... anyway) and we'll have to keep kicking it each 5.5 months to stay 'alive'.

If they wanted to hand their private key materials to the upstreams they could do the signing, but that seems icky (to me). I don't know that, if implications are understood by the end site and configurations available for use on their side, end-sites would want to hand over control of their IP assets in this way. Running the signing on their side should be simple enough, and low/no-cost. > And publishing something IMHO prematurely, locks the WG into that RFC, > making revising it much harder, than if it were still in-WG and > not-yet-published. I think the authors said something like: "send text" where you think it is fit to be inserted... If other folks want to delay/re-review they need to speak up. Consensus so far was that the document was ready to move along. -chris
