[cabfpub] givenName and surname revived

Wed Aug 24 11:07:54 UTC 2016

Bonjour,

givenName and surName are sufficient to specify an identity. More than one person may share this identity, but to me, BR don’t tend to distinguish them. There’s nothing in BR requiring CAs to generate certificates with canonical and non-ambiguous names. The non-ambiguity goal is achieved by following EVG only.

Given your example IV certificate, you’ll have givenName=John, surName=Doe, and also a country and either a localityName or a stateOrProvinceName. So you’ll know that this website belongs to someone named John Doe living in a specific city or state in this country, but nothing more.

If you want to follow ETSI 319412-1 rules and insert a serialNumber attribute to avoid name collisions, feel free, it’s not forbidden.

Cordialement,
Erwann Abalea

But givenName and surname are not sufficient to specify an identity. How many Robert Smiths exist in UK/US/CA ? (or Mario Rossi in Italy, as to that).

If I would like to know who's behind a web site whose SSL cert contains giveName=John, surname=Doe, I am none the wiser.

What do you mean by definition? I consider IV v. OV well defined because of the meaning associated with the OID inserted into the cert. Section 7.1.6.1 states “ {joint‐iso‐itu‐t(2) international‐organizations(23) ca‐browser‐forum(140) certificate‐policies(1) baseline‐requirements(2) individual‐validated(3)} (2.23.140.1.2.3), if the Certificate complies with these Requirements and includes Subject Identity Information that is verified in accordance with Section 3.2.3.” Section 3.2.3 is verification of an individual whereas Section 3.2.2 is verification of an organization.

Hi Jeremy,

My apologies, but can you clarify the section where IV certs are well defined? I see that “individual-validated” is stated twice in sections 1.2 and 7.1.6.1 (the same for domain-validated and organization-validated), but I can’t find the definition.

Thanks, Bruce.

Hey Bruce – IV certs are well defined. The goal of the ballot isn’t to further define IV certs but to permit use of the givenName and surname fields for IV certs. giveName and surname in the org field would be allowed. They’d still use the IV OIDs as they were validated under the IV section of the CP.

Hi Jeremy,

Would like some clarification. On the call yesterday, it was said that IV certificates were not defined, so this ballot will help resolve this.

Per 7.1.4.2.2 b, the current BRs allow givenName and surname to be included in the organizationName field. Will this still be allowed? If so, what would the certificate type be? OV or IV? I would prefer that these be OV certificates.

If we do make the changes and the CAs have to meet Microsoft’s requirement to put a DV, OV, or IV certificate policy in the certificate, I think we should clearly define each certificate type.

Also, the stateOrProvinceName field appears to currently have an issue as it does not have any language to address the case where there is no state or province in the address.

Thanks, Bruce.
