[cabfpub] EV Guidelines §14.2 delegation of functions to RAs etc.

Wed Aug 17 09:56:50 MST 2016

Adriano, I may not be understanding your original question -- but here is another possible answer.

If Company A applies for an EV cert for foo.com, the CA will do an EV vetting for the organization (Company A) and then for the domain (foo.com).  Under EVGL 14.2, it looks like Company A can then ask to be designated as an Enterprise RA - but only for the confirmed domain foo.com -- and then get certs for third level and higher domains that end in foo.com.  But Company A has not proven ownership or control of any other domains, such as bar.com, so is not an Enterprise RA for any other domains.

Now suppose Company A comes back to the RA and asks for a cert for bar.com.  In my opinion, the CA is not required to re-do EV organization validation for Company A again -- it can rely on the earlier EV organization validation (for the full 13 month period), so long as the CA is certain it is really dealing with Company A.  But it must do EV validation of bar.com to prove it is owned or controlled by Company A.  Once that has been done, Company A could ask to be designated as an Enterprise RA for bar.com also.  But there is no real connection between the status of foo.com versus bar.com, other than Company A may only have to go through a single EV organization vetting.

Is that responsive to your original question?

I don’t think this is a very high bar.  It would seem the following process would work:

1) Customer requests EV Enterprise RA privileges for example.com, example.net, corp.example.org, example.biz, …

2) CA follows EV issuance procedures and issues a single EV certificate that has all the base domains in it.  This certificate could have a CA-defined critical extension marking it an “Enterprise RA EV” certificate or some such to prevent it from being used on a server.  I think it could even have CA-generated key pair where the CA simply threw away the private key after generation.

3) If the customer wants new domains, the CA issues a new “Enterprise RA EV” certificate using the same process.  There does not appear to be a requirement that all domains be in a single certificate, so it could just be the new domains.

I think this would meet all the requirements that are set out.

Thanks,

Peter
