Re: LOAs for Cross Connects - Something like PeeringDB for XC

way back, the rirs were very insistant that their use of rpki authority
was most emphatically not to be considered an identity service.  this
permeated the design; e.g., organization names were specifically
forbidden in certificate CN, Subject Alternative Name, etc.


yup, I agree... though the b2b stuff George/Geoff have written up LOOKS like
it could be useful for this LOA type discussion. The spaghetti draft appears
to also fill this niche...

Neither are particularly rooted in the RPKI except that the CA certs are being
used as a method to attest that a 'thing' exists, and that something signed
that 'thing' as proof of knowledge (I guess, really). Effectively this is:
  1) I am 'ca-foo' in a tree that you can trust knows I am 'foo'.
  2) I signed this blob (LOA)
  3) I asked jane at bar.com to sign as well
  4) you can verify me (because rpki tree) and you can verify Jane because she's
      also using her RPKI ca cert.

this may be a little cumbersome to sort through, especially if all parties here
aren't party to the RPKI (did equinix plumb the RPKI into their customer portal
and all of the things required to make a x-connect work in this manner?), but I
imagine that if this gets wings it could be automated and it could be reliable
and all parties (except the colo folks perhaps?) may already have incentives
in places to use their RPKI goop for this function.

this would work only if the LOA is being sent to someone with whom my
contract is signed with a key validating through the same hierarchy, or
the credential was associated contractually.  i do not think equinix
is up to this yet.
