Reminder: Ballot 189 – Amend BR 6.1.7 to clarify signing by root keys - is in the voting period (ends APRIL 13).


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:
     *   The Root CA uses a 1024-bit RSA signing key that was created prior to the Effective Date;
     *   The Applicant’s application was deployed prior to the Effective Date;
     *   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;
     *   The CA follows a documented process to determine that the Applicant’s application poses no known security risks to Relying Parties;
     *   The CA documents that the Applicant’s application cannot be patched or replaced without substantial economic outlay.
     *   The CA signs the Subscriber Certificate on or before June 30, 2016; and
     *   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 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.
