[cabfpub] Ballot 189 - Amend Section 6.1.7 of Baseline Requirements

[Dimitris Zacharopoulos]

*Ballot 189 - Amend Section 6.1.7 of Baseline Requirements*

The following motion has been proposed by Dimitris Zacharopoulos of 
HARICA and endorsed by Bruce Morton of Entrust and Jeremy Rowley of 
Digicert

*Background*:

Section 6.1.7 of the Baseline Requirements states that the Root CA 
Private Keys MUST NOT be used to sign end-entity certificates, with some 
exceptions. It is unclear if this exception list includes end-entity 
certificates with EKU id-kp-timeStamping. This ballot attempts to 
clarify two things:

 1. that it affects Root Keys in a hierarchy that issues SSL
    Certificates and
 2. that it does not include time stamping certificates in the exception
    list.

It also clears the exception language for 1024-bit RSA Subscriber 
Certificates and testing products with Certificates issued by a Root.

*-- MOTION BEGINS --*

/Current section 6.1.7/

Root CA Private Keys MUST NOT be used to sign Certificates except in the 
following cases:

 1. Self-signed Certificates to represent the Root Certificate itself;
 2. Certificates for Subordinate CAs and Cross Certificates;
 3. Certificates for infrastructure purposes (e.g. administrative role
    certificates, internal CA operational device certificates, and OCSP
    Response verification Certificates);
 4. Certificates issued solely for the purpose of testing products with
    Certificates issued by a Root CA; and
 5. Subscriber Certificates, provided that:
     1. The Root CA uses a 1024-bit RSA signing key that was created
        prior to the Effective Date;
     2. The Applicant’s application was deployed prior to the Effective
        Date;
     3. The Applicant’s application is in active use by the Applicant or
        the CA uses a documented process to establish that the
        Certificate’s use is required by a substantial number of Relying
        Parties;
     4. The CA follows a documented process to determine that the
        Applicant’s application poses no known security risks to Relying
        Parties;
     5. The CA documents that the Applicant’s application cannot be
        patched or replaced without substantial economic outlay.
     6. The CA signs the Subscriber Certificate on or before June 30,
        2016; and
     7. The notBefore field in the Subscriber Certificate has a date on
        or before June 30, 2016

/Proposed section 6.1.7/

Private Keys corresponding to Root Certificates that participate in a 
hierarchy that issues Certificates with an extKeyUsage extension that 
includes the value id-kp-serverAuth [RFC5280] MUST NOT be used to sign 
Certificates except in the following cases:

 1. Self-signed Certificates to represent the Root CA itself;
 2. Certificates for Subordinate CAs and Cross Certificates;
 3. Certificates for infrastructure purposes (administrative role
    certificates, internal CA operational device certificates)
 4. Certificates for OCSP Response verification;

*These changes become Effective 30 days after the ballot passes.*
