> Alternative registration numbers for EV certificates
>
> Ballot SC17: Alternative registration numbers for EU certificates
>
> Purpose of Ballot: Allow for the inclusion of additional information in
>
> certificates in order to comply with relevant EU regulations.
>
> The following motion has been proposed by Tim Hollebeek of DigiCert 
> and endorsed
>
> by Dimitris Zacharopoulos of Harica and Enrico Entshew of D-Trust.
>
> Motivation:
>
> Update to CAB Forum EV Guidelines to cater for alternative 
> registration numbers
>
> caused by EU Legal Requirements:
>
> i. The EU Regulation No 910/2014 (eIDAS 
> [https://eur-lex.europa.eu/eli/reg/2014/910/oj])
>
>    defines regulatory requirements for certificates with an agreed 
> quality level
>
>    called Qualified. This regulation specifies in Annex IV specific 
> requirements
>
>    for “Qualified certificates for website authentication” including the
>
>    statement that the certificate shall contain: “for a legal person: 
> the name
>
>    and, where applicable, registration number as stated in the 
> official records,”
>
> ii. It is understood that this requirement relates to validated 
> attributes for
>
>    the identification of the certificate subject and hence is best 
> fitted in the
>
>    subject’s distinguished name.
>
> iii. In line with the regulatory framework ETSI has defined a general 
> structure
>
>    for carrying “registration numbers” in TS 119 412-1
>
>    [https://www.etsi.org/standards-search#page=1&search=TS119412-1] 
> clause 5.1.4.
>
>    This uses the X.520 
> [https://www.itu.int/rec/dologin_pub.asp?lang=e&id=T-REC-X.520-201210-S!!PDF-E&type=items] 
>
>
>    organizationIdentifier within the subject’s distinguished name in 
> line with its
>
>    stated purpose being “holds an identification of an organization 
> different
>
>    from the organization name”. This is used for ETSI requirements to 
> carry
>
>    registration numbers for certificates, Qualified or otherwise.
>
> iv. It is considered that this use of organizationIdentifier supports 
> the primary
>
>    purpose of EV certificates as stated in section 2.1.1 of the EV 
> Guidelines as
>
>    “other disambiguating information”.
>
> v. A recent EU delegated Regulation 2018/389 on secure communications 
> for payment
>
>    services (RTS 
> [https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX%3A32018R0389])
>
>    states in Article 34.2 that for Qualified Website certificates 
> (QWACs) the
>
>    registration number required in eIDAS “shall be the authorisation 
> number of the
>
>    payment service provider … or equivalent [reference made to earlier 
> regulations
>
>    relating to banks]”.
>
> vi. ETSI has specified TS 119 495
>
>    [https://www.etsi.org/standards-search#page=1&search=TS119495] 
> requirements for
>
>    carrying PSD2 related registration numbers in the general structure 
> for
>
>    registration numbers defined in TS 119 412-1 clause 5.1.4 as 
> mentioned in
>
>    iii. above.
>
> vii. ETSI has endeavoured to ensure and always intended that 
> requirements relating
>
>    to web site certificates at the Qualified level are in line with 
> the CA/B Forum
>
>    EV Guidelines.
>
> viii. This proposal only includes some of the Registration Schemes as 
> used in
>
>    ETSI TS 119 412-1, which have clear validation rules (NTR, VAT, 
> PSD) that provide
>
>    reasonable assurance in line with the EV Guidelines. The IPR for 
> the semantics
>
>    of this scheme is proposed to be released to the CA/B Forum 
> allowing it to
>
>    further extend the use of organizationIdentifier to include other 
> Registration
>
>    Schemes (e.g. LEI) and corresponding validation rules, at the CA/B 
> Forum’s
>
>    discretion. Also, any further changes by ETSI to ETSI TS 119 412-1 
> will not
>
>    impact the CA/B Forum.
>
> ix. Having found out that CA/B Forum’s interpretation of EV 
> Requirements in section
>
>    9.2.8 “Other Attributes” was not in line with those understood by 
> ETSI experts,
>
>    ETSI would like to harmonise with CA/B Forum approach to carrying 
> alternative
>
>    forms of registration number for PSD2 and other registration schemes.
>
> b) CA/B Forum specific concerns are:
>
> i. Requirements regarding Attributes to be included in the Subject DN 
> need to be
>
>    explicitly covered in 9.2.
>
> ii. Organisations may wish to identify OrganisationalUnits within 
> their organisation.
>
>    It is unclear if this is currently allowed in the EV Guidelines 
> (similar
>
>    ambiguity in section 9.2.8).
>
> iii. There are objections to ETSI specific usage of the orgID field 
> (no squatting).
>
> iv. The procedures for validation of the attribute need to be clearly 
> stated.
>
> v. There may be other uses of the organizationIdentifier field in 
> various PKIs,
>
>    however it is not considered to be a problem. Because of the unique 
> semantics we
>
>    are specifying for each identifier, applications should be able to 
> understand
>
>    different uses of the OrgID field by different issuers and users. 
> There are many
>
>    different "PKIs" out there that can use all X.500 attributes 
> differently and with
>
>    different validation or no validation at all. To the best of our 
> knowledge, the
>
>    WebPKI has never used this subjectDN attribute before for 
> Publicly-Trusted
>
>    Certificates. Thus there is no "conflict" by using this attribute 
> in the EV
>
>    Guidelines for SSL/TLS Certificates, and perhaps later for EV Code 
> Signing
>
>    Certificates.
>
> vi. This use of organisationIdentifier must be extendable to allow for 
> use by other
>
>    registration numbers allocated by different registration schemes. 
> Some CAB Forum
>
>    members have indicated interest in carrying registration numbers 
> other than for
>
>    Incorporation within EV Certificates. This is catered for in the 
> current proposal.
>
> vii. There is interest by some CA/B Forum members in carrying LEIs 
> within CA/B Forum
>
>    certificates but as yet the LEI registration scheme is not 
> currently considered
>
>    sufficiently robust to be recognised as an registration numbering 
> scheme to be
>
>    accepted by CA/B Forum. Therefore this proposal only introduces a 
> limited set of
>
>    Registration Schemes (namely NTR, VAT, PSD) which have reasonably 
> robust
>
>    validation rules.
>
> viii. Some CA/B Forum members have indicated the possible need for 
> multiple
>
>    identifiers in the subject name. This, however, cannot be achieved 
> using X.520
>
>    organizationIdentifier which defined this attribute as being 
> “SINGLE VALUE”.  The
>
>    use of a single value has the advantage is it is clear what is the 
> registration,
>
>    in addition to the company registration, which identifies the subject.

> ---MOTION BEGINS---
>
> Purpose of Ballot: Update to CAB Forum EV Guidelines to allow alternative

> Proposed Ballot for Changes to EVG 1.6.9
